The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

07/06/2026 Clean Technica Fixing Climate Communications Part 1 - Make consequences such as your insurance bill, your home, and your children’s health urgent and tangible; make the cause concrete by anchoring every message to pollution rather than climate change; and make the cure feel expansive rather than restrictive. Reaching enough people to sustain the transition will require a delivery infrastructure built around genuine community engagement, economically grounded wins, and a willingness to hold accountable the interests that have made this conversation harder than it needs to be.

07072026 Clean Technica Climate Communications — From Losing the Argument to Winning It Part 2 - Telling the climate story with the value proposition of cost, risk management, improved operational performance, supply chain resiliency, and long-term enterprise value is a winning one. It’s a strategy that appeals to the C-suite, is durable, and can be couched in shareholder returns.

07/06/2026 Smithsonian Magazine These 11 Wildlife Images from the Ocean Conservancy’s Photography Contest Showcase the Wonder of Earth’s Waters - The annual contest received more than 1,000 photographs of marine wildlife and habitats this year. The ones that rose to the top were portraits of ocean wildlife, and I think that’s because we crave to see and connect with animals on an interpersonal level.

07/07/2026 The Conversation 3.1 billion‑year‑old rocks in Australia reveal a forgotten chapter of Earth’s water cycle - We learn the water cycle in school as a story of evaporation and precipitation. But Earth runs a second, far slower one deep beneath our feet. On the ocean floor, seawater seeps into the oceanic crust and reacts with the rock, becoming chemically bound inside its minerals, locked into their crystal structures rather than sitting as free water. Over millions of years, sinking tectonic plates carry these water-bearing minerals down into the mantle, the hot rock layer beneath the crust. This sinking of one plate beneath another is called subduction, and volcanoes eventually breathe the water back out. The deep water cycle moderates Earth’s water budget. At the surface, it keeps the oceans from drying up or drowning the continents, while in the interior, it changes how the mantle melts and builds continents.

07/06/2026 NWF Blog Marine Animal Quiz: It’s Plastic Free July! - Take the time to learn more about how plastic pollution in the oceans of the world harms marine life and consider action steps you can take to reduce your plastic waste footprint.

07/04/2026 ScienceDaily The secret to healthy aging may be hidden in your blood - A new study found that centenarians have a unique chemical "fingerprint" in their blood that sets them apart from normal aging, including unusual patterns of bile acids and steroids linked to longer survival.

07/03/2026 Planetizen Lake Powell reaches lowest water level on record - Currently, Lake Powell is around 24 percent full. The last time it was completely full was in 1983. Since then, water levels have fluctuated, but in 2026, they have fallen to a critical point. And there are multiple concerns if the water levels continue to drop. One includes reaching "dead pool," the point at which water levels are so low that water can no longer move across the dam and into the Grand Canyon, which would cause significant ecological impacts and reduce the capacity for hydroelectricity. 

07/03/2026 Yale Environment 360 In Overfished Adriatic Sea, Dolphins Look to Trawlers for Food - Off the eastern coast of Italy, large numbers of bottlenose dolphins are looking to fishing trawlers as a source of food, a sign that dolphins may be struggling to feed themselves in waters depleted by overfishing. Dolphins may also suffer hearing damage that results from chronic exposure to the noise of trawlers. It is risky behavior. However, finding sufficient prey away from trawlers in an overfished sea may be too difficult. It appears that for these animals, taking the risks is better than going hungry.

7/2/2026 Smithsonian Magazine Earth Might Be Home to 20 Million Insect Species—More Than Three Times as Many as Previously Thought – Only about one million species have been named and described, meaning up to 95 percent of the planet’s insect diversity might remain a mystery…. With more than 40 percent of known insect species threatened with extinction. “The library is being burned before the books can be read.”

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

06/17/2026 Science Daily Scientists say most of what’s in your food is still a mystery - Most chemicals in food are invisible to us in terms of research. We consume them every day, but we have little idea what they do. Projects such as the Foodome Project are now attempting to catalogue this hidden chemical universe. More than 130,000 molecules have already been listed, linking food compounds to human proteins, gut microbes and disease processes. The aim is to build an atlas of how diet interacts with the body, and to pinpoint which molecules really matter for health.

06/17/2026 The Conversation Levels of ‘forever chemicals’ in dolphins and whales are rising globally - Whales and dolphins inhabit some of the largest and seemingly most pristine environments on Earth, from tropical coastlines to Antarctic waters. Yet even they cannot escape PFAS – persistent “forever chemicals” that leak from our homes, factories and waterways into the sea. Whales and dolphins inhabit some of the largest and seemingly most pristine environments on Earth, from tropical coastlines to Antarctic waters. Yet even they cannot escape PFAS – persistent “forever chemicals” that leak from our homes, factories and waterways into the sea. Some dolphin studies have reported changes in immune-related markers associated with PFAS exposure. The highest concentrations tended to be found in coastal dolphins and porpoises, suggesting animals living near urban and industrial areas face greater exposure.

06/15/2026 Smithsonian Magazine Venus Flytraps Snap Their Traps Shut in Less Than a Second - A team reports that the chomping motion happens when rigid walls of cells on the leaves’ outer surface suddenly soften. The findings provide new insights into plant biology and could inspire new robotic designs.

6/16/2026 The Conversation Microplastics are everywhere in Pennsylvania’s water – but the tide may be turning - Microplastics are nearly everywhere, their concentration in sediment has been doubling every 20 years, and some of the most common types are among the most toxic. More than 80% of mismanaged plastic waste - plastic that’s littered, dumped or otherwise not properly contained - is estimated to be transported by rivers to coastal environments. What can you do to decrease your exposure to microplastics and help decrease their spread? You can stay informed about which plastics carry the greatest health risks and check the recycling number on the bottom of containers before you buy. You can also swap out single-use plastic cups, straws and food containers for alternatives, such as glass, stainless steel or unbleached paper.

06/11/2026 NASA Air Pollution’s Daily Pulse Over the Northeast - More than 35 million people live along the New York–Washington corridor and breathe the region’s air. While air quality has improved significantly in recent decades, outbreaks of ground-level ozone remain common, particularly in the warm summer months, when the chemical reactions that produce the pollutant accelerate and stagnant air allows ozone to accumulate. A reminder of this seasonal phenomenon came earlier than usual in 2026, when a mid-May heat wave prompted the New York State Department of Health and the New York Department of Environmental Conservation to issue a health advisory on May 17 over concerns about ozone.

06/13/2026 Clean Technica Solar & Storage Provide Over 90% of All New Power Added to the U.S. Grid in Q1 - The United States added 7.8 gigawatts (GW) of new solar capacity in the first quarter of 2026, surpassing 6 million cumulative installations as solar remained the leading source of new power added to the grid. Despite changing tax policy and regulatory actions targeting clean energy, solar and energy storage represented 91% of new capacity installed in Q1 as utilities, homeowners and businesses seek energy security amid global gas and gas turbine supply disruptions.

03/17/2026 National Geographic To study microplastics, Cassandra Rauert first had to build a plastic-free lab. It wasn't easy - An air-locked, 250-square-foot facility built almost entirely from stainless steel and nicknamed “the submarine”—though it feels less like a sub and more like a starship from a galaxy where plastic never took over modern life. Known as the Minderoo Plastics and Human Health Laboratory

06/09/2026 Science Daily An invisible forever chemical rain is falling across the planet - Researchers found that refrigerants and certain anesthetic gases have generated more than 335,000 tons of trifluoroacetic acid (TFA), a highly persistent "forever chemical," that has been deposited across Earth's surface since 2000. The pollutant is now showing up everywhere from rainwater to remote Arctic ice, and scientists expect levels to keep rising. Scientists are still working to fully understand the long-term effects of TFA. The European Chemicals Agency classifies the chemical as harmful to aquatic life. Researchers have also detected TFA in human blood and urine. In addition, the German Federal Office for Chemicals recently proposed classifying TFA as potentially toxic to human reproduction.

06/09/2026 National Wildlife Federation Data Centers are Driving Up Your Energy Bill - Clean energy has become the cheapest form of energy, but wind and solar still only account for 17 percent of the country’s energy generation. The biggest barrier to deploying clean energy is usually transmission. Without enough transmission to deliver cheaper clean energy to where it’s needed, over 900 GW of solar and wind projects sit waiting in queue, and utilities often default to more expensive fossil fuel generation instead. We can double down on outdated systems that pollute our air and water and drive up prices, or we can invest in the resilient energy solutions that have proven to be the cheapest, build the grid needed to deliver them, and ensure the largest electricity users pay their fair share of the costs they trigger.

06/08/2026 National Parks Traveler Young Mountains, Old Rocks: A Geological Overview of the Teton Range - The Tetons continue to grow. The tectonic forces that built the range are still active, and stress continues to build even if the Teton Fault has not experienced major movement in recorded history. Evidence of ongoing stress appears east of the Teton Range, where the Snake River does not flow down the center of its riverbed. Instead, the river flows preferentially along the western side of its banks as the extensional stress builds and the eastern block of the fault (the block underlying Jackson Hole) tilts more westward.

Field Trip Reconnoiter

/

I’ve been busy working on the curriculum of the core training to be offered next fall by my local Missouri Master Naturalist chapter. One of the field trips we had added to the curriculum was unfamiliar to everyone….but had been one the places featured in a 2025 Ozark Public Television production called Wild Ozarks. Four of us participated in a reconnoiter trip to the place last week.

Wow! It is a great place for a field trip.

Easy to get to from Springfield

Springs and sinkholes

Remediated riverbank…and ash trees (dead or dying) replaced with other tree species

Tree cavities

Some invasives but not overwhelming

Road or mowed trail for hiking

Pawpaw patch

And much more!

I loved the handmade tree signs!

We modified the plan to divide the students into 4 groups rather than 3 (so 6-7 students/group) and the topics will be: forest ecology, geology (karst), tree identification (using dichotomous key), and nature journaling/nature observation.

I am looking forward to seeing the place in the fall….and observing the students discovering this special place.

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

5/1/2026 Science Daily A hidden brain “cleaning” effect triggered by movement - Every time you tighten your abdominal muscles—even slightly—your brain may gently sway inside your skull. This subtle motion, triggered by pressure changes in connected blood vessels, appears to help circulate cerebrospinal fluid around the brain, potentially flushing out harmful waste.

4/30/2026 NWF Blog Fighting Toxic “Forever Chemicals” on Our Farms - The Department of Defense has identified over 4,000 high-risk or already-contaminated agricultural sites across the U.S.  The PFAS contamination often came from ‘biosludge’ from local wastewater treatment plants that was spread of field as cheap fertilizer before the PFAS danger was understood. But we know how to fix this: ban PFAS at the source, regulate what’s left, and clean up what’s left without leaving the people who have already suffered to pay.

4/30/2026 Clean Technica The Petroleum System Is Entering Its Volatile Decline Phase - he UAE’s decision to leave OPEC+ is not just another Gulf oil story. It is an early signal of what happens when a producer with low-cost barrels, spare capacity ambitions, and a long view of electrification decides that flexibility may be worth more than cartel discipline. Oil demand is beginning to bend under the weight of EVs, electric trucks, efficiency, remote work, substitution, and changing logistics. The petroleum system is more likely to become less stable as it declines, because the institutions, companies, states, supply chains, and fiscal bargains built around oil were built for growth. A declining oil market does not just reduce demand. It changes incentives.

4/29/2026 NPR Baby teeth hold clues to the harms of toxic metals for infants — and older kids – A study of the baby teeth shed by 500 children in Mexico City…. s the children reached adolescence, the researchers also took detailed behavior assessments for some of the kids and MRI scans of their brains. The researchers looked at exposures to nine metals common in the environment. It's not just how much of these metals babies are exposed to that matters, but when that exposure happens. Exposure to this metal mixture during this critical period of around 6 to 9 months of development was strongly associated with negative changes in behavior in these adolescents including inattention and hyperactivity. They also found a strong link to changes in the brain, including a decrease in overall brain volume and changes in the way different areas of the brain connect with each other. They also found abnormalities in the brain's white matter, which is important to the speed and efficiency of thought.

4/30/2026 Archaeology Magazine Skeleton Study Reveals Life on the Frontier After the Fall of Rome – 250 sets of human remains in Southern Germany from between AD 400-700. After the Roman Empire fell in A.D. 476, the study suggests that life expectancy rose to 43.3 years for men and 39.8 years for women. Women are thought to have had a lower life expectancy due to the risks of childbirth, but the overall rise in life expectancy may have been due to fewer violent conflicts in the region. The study also determined that in the late fifth century, after the collapse of the Roman Empire, northern Europeans mixed with diverse Roman provincial groups as people migrated north into southern Germany and away from Roman territory. By the seventh century A.D., the population living in the area had become genetically similar to today’s Central Europeans.

5/1/2026 National Parks Traveler Climate Change Is Altering When Water Is Available - In the Upper Midwest and New England, streamflow has already become more evenly spread throughout the year due to climate change. In contrast, patterns in the western United States are more complex. I n snow-dominated regions of the U.S. West, warmer years tend to produce a wider distribution of streamflow across the year—conditions that may benefit senior water users while disadvantaging junior users. In non-snowy parts of the region, the opposite pattern emerges: warmer years are associated with more concentrated flows, potentially offering a relative advantage to junior water users.

4/29/2026 Yale Environment 360 How the Next El Niño Could Lock in a Hotter Climate - In a world already superheated by greenhouse gases, a strong El Niño during the next 12 to 18 months could permanently push the planet’s average annual temperature past the 1.5 degrees Celsius warming threshold. The potential for more destructive physical impacts raises deeper concerns about how societies that developed under relatively stable climate conditions will function in a world with shifting baselines and sharper swings between droughts and floods, more intense tropical storms, expanded fire seasons, and long-lasting unseasonal extreme heat.

4/29/2026 Smithsonian Magazine Video of a Sumatran Orangutan Crossing a Human-Made Wildlife Bridge in the Treetops - The human-made treetop overpass stretches across the Pakpak Bharat district’s Lagan-Pagindar road, which runs through the habitat of about 350 wild orangutans and separates the Siranggas Wildlife Reserve from the Sikulaping Protection Forest.

4/28/2026 The Conversation A probe into ‘forever chemicals’ in activewear lays bare fashion’s greenwashing problem - While most major brands promised to phase out PFAS by 2020, follow-up testing shows they still appear in leggings and sports bras across the sector. The transition has been slow because finding safer alternatives that perform just as well is both expensive and technically complex. Until we move from a system of voluntary promises to one of legal requirements, “sustainable” will remain a marketing choice rather than a guarantee.

4/29/2026 Science Daily Earth is splitting open beneath the Pacific Northwest - Scientists have, for the first time, clearly captured a subduction zone in the act of breaking apart. These zones form where one tectonic plate sinks beneath another, and they are responsible for some of the most powerful geological events on Earth.

Missouri Capitol

/

Before the Missouri Department of Conservation Partners Roundtable began in Jefferson City, I toured the state capitol. I signed up in advance for a guided tour and arrived early enough to walk around the museum area.

I took pictures of the outside of the building. It was completed in 1917 after the previous building burned.  There is a large statue of Thomas Jefferson…and large columns.

I didn’t take many pictures of the museum part of the building although I did like the stone/mosaic of the ladies room…and the fossils in the walls.

The tour guide was informative and kept our group moving. I enjoyed the tour more than I would have walking around on my own and there were some areas that are not accessible except on the tour. We saw lots of murals,

Architectural details (including what the walls that are now painted white looked like originally).

And skylights.

I liked that bust of Sacajawea. There were others too…but that was the one area I felt rushed.

I liked that bust of Sacajawea. There were others too…but that was the one area I felt rushed.

After the tour, I went down to the basement cafeteria and enjoyed a piece of cheesecake…and purchased a salad to eat for lunch a few hours later.

As I walked away from the capitol, I noticed the mature sweet gum and bald cypress trees on the grounds.

Before I left Jefferson City to drive home, I visited Serenity Point at Noren Access.

It’s a place where the Capitol building can be seen from across the Missouri River. It was a good last vista before getting on the highway.

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Can Italy Protect Its Cultural Heritage from Naughty Tourists? - Each summer, as millions of tourists swarm into historic towns full of monuments and museums, a predictable kind of headline is sure to follow about badly behaved tourists putting cultural heritage at risk.

Bans on highly toxic pesticides could be a simple way to save lives from suicide - Pesticide poisoning is a common method of suicide in many low- to middle-income countries. Substituting highly toxic pesticides for less fatal ones can save lives. A cast study from Sri Lanka.

Federal Hurricane Forecasting Saves Lives & Money - A 5-day forecast in 2025 is roughly equivalent to a 2-day forecast in 2005, meaning lead times and path estimates have significantly improved, to the tune of 50% in the past 20 years. This helps save lives and has also led to an estimated 2 billion dollars in savings per storm. NOAA’s research arm, the Office of Oceanic and Atmospheric Research (OAR), houses not only the laboratories that help improve predictions, but much of the monitoring and observation infrastructure — like ocean buoys and gliders — that feed real time data into hurricane models, improving their accuracy and saving lives. The U.S. fully relies upon NOAA for our hurricane forecasts, including sea level rise and flooding. There is no other body ready or funded to pick up that work. The President’s budget proposed completely eliminating the research arm of NOAA.

Bison Benefits - A new study out this past week explains why bison are more beneficial for grasslands than traditional livestock, and the benefits increase as herd size does. A podcast from National Parks Traveler.

4 Reasons to Choose Plastic Free, All Natural Fibers Over Synthetic Fibers - Manufacturers give our fabrics trade names, so even when we look at the fiber content label inside our clothing, it isn’t clear that it is made from plastic. Buying clothing that is made from natural fibers is the fastest and safest way to save our planet.

An Explosive Beginning for Lake Bosumtwi - Bosumtwi’s exotic geology has drawn attention to the crater for economic reasons as well. When the asteroid struck, the shockwave fractured the crust around the crater, creating an extensive network of faults and cracks that allowed hot fluids to circulate. The event helped concentrate gold and other minerals from a gold-bearing rock layer called the Birimian Supergroup near the surface and primed the area around the crater to become a target of small-scale gold mining.

Common painkillers like Advil and Tylenol supercharge antibiotic resistance - Researchers discovered that these drugs not only fuel bacterial resistance on their own but make it far worse when combined with antibiotics. The findings are especially troubling for aged care settings, where residents commonly take multiple medications, creating perfect conditions for resistant bacteria to thrive.

See the Rare ‘Electric Blue’ Lobster Found Off the Coast of Massachusetts – A video showing a vibrantly colored shell that results from a genetic mutation affecting pigmentation.

New Jersey Cats Caught on Camera – Bobcats caught on camera traps…and other animals in the wilds of New Jersey.

Traveling Photographer Spends 17 Years (And Counting) Documenting Indigenous Cultures – Faces and clothes from around the world.

The surprising foods that lead to better sleep - It seems that a plant-rich diet is the most beneficial for sleep, for numerous reasons – and that eating at consistent times throughout the day – for those who can – may also help.

Fantastic Caverns

/

Fantastic Caverns is a great place to visit in the summer since the cave is 60 degrees all year long. We arrived a little before 10 AM and got tickets for 10:30 since there was a large school group at 10. During the wait, I bought some goat milk soap in the gift shop and looked at the mineral, quilt, and other artifact displays in the visitor center.

At 10:30 we walked out of the visitor center, down a ramp, and got on the tram that would take use through the cave.

I managed to take more pictures of the entrance (man-made) as we started our tour than I did during my previous visits. There is a lot of Viriginia Creeper on the rock face.

I used the ‘night scene’ setting on my Canon Powershot SX730 HS (my oldest camera!) because it is easier to hold than my phone. The lighting in the cave is relatively good and the guide illustrated several ways lighting of the cave has changed over the years. This was my third visit, and this guide was probably less experienced that my previous visits. (click on any image below to see a larger version).

This was the first visit to the cave for my daughter and the second for my husband. We all agreed that it is an excellent option for visitors that are not physically able to do other caves. We are already planning a visit to a cave that offers ultraviolet light tours…but that requires being able to walk around on your own with a headlamp and googles!

Ed Clark Museum of Missouri Geology

/

My daughter and it did a day trip to Rolla MO to see the Ed Clark Museum of Missouri Geology last week. The forecast was for rain but it paused just as I got to my daughter’s so I took some pictures of the buds on the yuccas near her driveway.

There was another pause when we got to Rolla and stopped for lunch. It was beginning to sprinkle as we walked into the Missouri Department of Natural Resources that houses the museum. We discovered that they keep the front door locked – the receptionist must come out to let people in. We were the only visitors! The museum is not large, but the contents is almost all from Missouri and the labels are good. As usual – I took pictures.

Some of my favorites were things that I recognized: blue chert, galena, crinoid fossils, imprints of ferns, trilobites. stomatolightes

There was a glacial erratic from a banded iron formation found near Moberly, Missouri…hadn’t expected to see something like that.

I thought there would be a store associated with the museum…didn’t see any indication that it existed. They did have copies of the most recent Missouri Resources publication. It appears that the previous issues are available online, but the most recent one is part of a new blog feature (Missouri Resources Online) that they are working on; it wasn’t visible yet. I had been thinking of buying some Missouri geology maps to hang on my basement wall and I’m not sure where they can be purchased since the store was not there. Maybe printed maps are too much a ‘thing of the past.’

It rained for almost the whole drive home (almost 2 hours). We didn’t have any accidents on our side although we did see a lot of emergency vehicles on a side road we could see from Interstate. My daughter looked since I was driving. Evidently there was water covering a lot of the side road (and she said it looked deep). A little further along there was an accident on the opposite side of the Interstate that closed one of the two lanes on that side. I was glad when we made it back to Springfield.

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Warming Linked to Rising Cancer Rates Among Women in the Middle East - As temperatures in the region rose, so did cancer rates in Qatar, Bahrain, Jordan, Saudi Arabia, the United Arab Emirates, and Syria, which are prone to extremely hot summers. Increasingly extreme heat is making air pollution worse, weakening our immune systems, and putting additional strain on hospitals. These and other factors could be driving up the risk of cancer.

90-Year-Old Korean Artist Kim Yun Shin Is Finally Going Global – Creative longevity!

Archaeologists Unearth Two Rare African Figurines in 1,500-Year-Old Christian Burials in Israel - The artifacts are carved from rare ebony wood that originated in India or Sri Lanka. Each figurine features a small hole through which a cord might have been threaded, allowing the owner to wear it around their neck.

When Sears Pioneered Modular Housing - In an early iteration of modular housing, kit homes were sold by companies like Sears and Montgomery Ward in the early and mid-20 century - complete with “all the materials that a kit home purchaser needed to build the home, including at least 10,000 pieces of precut lumber to suit the model of the home, drywall, asphalt roof shingles, carved staircases, and the nails, door knobs, drawer pulls, paint and varnish needed to do the job. Electrical, heating systems, and plumbing materials could also be purchased at extra cost.”

Scientific breakthrough brings CO2 'breathing' batteries closer to reality - Scientists have made a breakthrough in eco-friendly batteries that not only store more energy but could also help tackle greenhouse gas emissions. Lithium-CO2 'breathing' batteries release power while capturing carbon dioxide, offering a greener alternative that may one day outperform today's lithium-ion batteries.

Fitness fight: Native bees struggle against invasive honey bee - High densities of European honey bees could be harming Australian native bees' 'fitness' by reducing their reproductive success and altering key traits linked to survival. Has this happened in North America as well?

Ancient pollen reveals stories about Earth’s history, from the asteroid strike that killed the dinosaurs to the Mayan collapse – Missouri rocks: When an asteroid struck Earth some 66 million years ago, the one blamed for wiping out the dinosaurs, it is believed to have sent a tidal wave crashing onto North America. Marine fossils and rock fragments found in southeastern Missouri appear to have been deposited there by a massive wave generated by the asteroid hitting what is now Mexico’s Yucatan Peninsula. Among the rocks and marine fossils, scientists have found fossilized pollen from the Late Cretaceous and Early Paleocene periods that reflects changes in the surrounding ecosystems. The pollen reveals how ecosystems were instantly disrupted at the time of the asteroid, before gradually rebounding over hundreds to thousands of years.

A New, Shape-Shifting ‘Flapjack’ Octopus Has Been Discovered in the Deep Sea Off the Coast of Australia - The tiny cephalopod grows only about 1.6 inches across, but it can survive more than half a mile beneath the ocean’s surface. During the 2022 expedition, the team used high-tech cameras, nets and sleds to collect samples and snap photographs deep below the ocean’s surface. Many of the specimens they found are thought to be new species.

Fast food, fast impact: How fatty meals rapidly weaken our gut defenses - Researchers discovered the gut protective protein, IL-22, was rapidly depleted in mice after just two days of eating high-fat foods.

Where To Go Caving in the National Park System – Mammoth Cave, Carlsbad Caverns, Wind Cave, Crystal Cave in Sequoia, Jewel Cave, Lehman Caves in Great Basin. I have been to all of them except Crystal Cave and Lehman Caves. Mammoth Cave would be the closest for me to see again.

Geology Field Trip (2)

/

After eating our picnic lunch at the Springfield Conservation Nature Center, we headed out to stops along US 65 headed toward Branson. Our second stop (the nature center was the first) was at the MoDOT parking lot on East River Bluff Blvd. We walked across River Bluff and down onto the triangular shaped parcel of land between the southbound entrance ramp and US 65. There are outcropping there with fossils….including crinoids which are the state fossil of Missouri. There were flowers blooming along the roadside on our way to and from the fossils.

Here are the small fossils I picked up

We were in the Burlington part of the rock column. Most of us took pictures of the reference page our guide showed us to help us understand what we were seeing.

The third stop was the Ozark Post Office which is not far from US 65 and is across the street from a road cut that shows the boundary between the Burlington and Elsey layers.

The fourth stop was at the Branson (Saddlebrook) Welcome Center. We walked north on the west side of US 65 until we could see the roadcut on the east side of the highway. The rocks are all in the Cotter layer. The black weathering is from manganese in the rock. The area was an ancient tidal flat; the V shaped structures in the rock are channels where the water flowed in and out.

The fifth stop was also in the Cotter layer…and was an area to see fossilized stromatolites! We pulled into a wider shoulder area off US 65 just north of Saddlebrook Dr. There were layers of shale where water was trickling out and plants were beginning to grow.

My knee was hurting enough that I did not climb to the top of the road cut (via a drainage channel) to see the stromatolites from the top, but I did observe them from the base of the roadcut. They look a bit like a funnel.

I also picked up rocks: patterns of ancient ripples and a sandwich (thin layers of bluish chert with sandstone between them).

The sixth stop was a bit further north on US 65 to see the Highlandville Fault…where there is a crack in the face of the roadcut clearly visible.

So much to see…we ran over our allotted time by more than an hour!

Geology Field Trip (1)

/

The geology field trip associated with the university class I took this spring was cancelled because of weather, but the one that was a follow-up to a Missouri Master Naturalist lecture happened on a beautiful spring day in early May! We started out at the Springfield Conservation Nature Center…the longest hike of the trip with stops along the way to see examples of

  • (Chert nodules)

  • Sedimentation – erosion and deposition

  • Soil creep

  • Bluffs and rock fall

  • Spring

  • Sinkhole

  • River meandering

Most of my pictures were not about geology! I noticed the turtle and water plants in the sedimentation area. It is easier to take pictures of landscapes than geologic features. The hike was over boardwalk and forest trails. The only place the trail was muddy/wet/slippery was where the spring water ran over it. Overall, it was a great hike…and I was ready for lunch afterward. If I do the hike again on my own, I will take it a bit slower; I’ve learned that my knees get sore with a lot of walking on uneven surfaces.

The botanical highpoint of the day was wild ginger in bloom!

A jack-in-the-pulpit was a close second.

From a tree perspective, seeing a young sassafras and a black locust in bloom was great too.

Near the nature center – there are plantings of native wildflowers. They had a cage around the lady slipper orchid that was blooming.

More tomorrow on the rest of the Geology Field Trip…

Learning about Missouri Geology – April 2025

/

In late March – after the monthly Missouri Geology post, my daughter and I visited Cedar Gap Conservation Area. I posted about the vegetation (spring wildflowers) and the tail itself here and saved the ‘rock’ pictures for this post. Most of the pictures are from along the trail.

The most interesting rock of the trip was found down near the stream by my daughter; I’m not sure how she found it in the jumble of rocks!

The geology lab for Missouri Master Naturalists that was a follow up to the geology program I’d arranged for last February focused on minerals. There were 8 sets of trays with a total of 24 minerals and we practiced the process to identify them! It was a learning experience. I realized that there might have been a better class for learning to id rocks and minerals than the geology course I am taking….and it is for educators (not sure that non-degree seeking students can take it).

Last week my daughter and I visited Onondaga Cave and Bennett Springs State Park….I’ll be posting about that trip soon. Both had a geology component too.

Geology Course Experiences – April 2025

/

Over the past month, the online geology course has moved along slowly with only another 2 chapters covering waste management/landfills and landslides. There was a week-long pause for Spring Break. I am glad I chose this version of the geology class (It’s titled ‘Earth: The Survival Guide’) since it provides a background for items in the news that have a geologic component. The syllabus for the next few weeks shows a significant uptick in topics with 4 chapters before the last exam on May 1. It seems like the course pacing is dramatically skewed toward the end.

I was disappointed that the scheduled field trip day was canceled because of weather (rain the previous days and the scheduled day, flash flooding and river flooding). Evidently there is not going to be another attempt. I’ll have to make do with my own observations as I travel around the state…and the geology field trip with Missouri Master Naturalists that is scheduled for early May; hopefully the weather will be better for that one.

The labs were also impacted by spring break. Topics were:

  • Groundwater contamination investigation that involved samples to be tested for nitrates, total dissolved solids, pH, and salinity…then pinpointing where contamination was coming from using a contour map of industries and where the samples were collected.

  • Streams and rivers using topographic maps to observe how river move along the surface and the observable structures from the interactions between water and the surface (things like natural levees and oxbow lakes).

  • Geologic maps – looking at the geographic distribution of rock units exposed at the Earth’s surface. Maps of Webster County MO, Bright Angel Quandrangle, AZ (part of the Grand Canyon), and the Williamsville Quadrangle, VA (part of the Appalachian Mountains).

The ‘streams and rivers’ lab was not on the original syllabus and there has not been an update showing which of the labs will be dropped. I hope the ones on Caves/Karst and Shorelines will still be part of the semester.

I am anticipating a flurry of activity between now and the end of the semester! There are a lot of textbook chapters in the syllabus that we haven’t done yet.

Learning about Missouri Geology – March 2025

We took two road trips over the past month --- opportunities to observe Missouri geology along the roadsides! My copy of Roadside Geology to Missouri has been a good reference.

The first was from our home near Springfield MO to St. Louis. Interstate 44 dominates the route and there are plenty of roadcuts first on the Springfield Plateau then the slightly lower Salem Plateau…finally down the northeastern flank of the Ozark Dome close to St. Louis. Our day trip was on a sunny day, so it was easy to take pictures.

One of the most interesting road cuts is at the north side of the rest stop near mile marker 235. The Roadside Geology book says – “Tilted blocks of Pennsylvanian sandstone and shale….are part of a down-dropped block of rocks along a fault zone or a filled-sink structure, or perhaps both.” I took pictures from the south side of the road as we were going toward St. Louis

And then one as we passed by on the return.

We noticed caves and state parks along the way and are planning a ‘field trip’ in April to see some of those.

The second was from our home near Springfield MO to Loess Bluffs National Wildlife Refuge near Mound City MO. The route took us from the Springfield Plateau to the Salem Plateau…then the Osage Plains as we turned toward Kansas City and crossed the Missouri River…finally to the Glaciated Plains of Northern Missouri. The day was sunny, making photographs of road cuts as my husband drove possible. I even got two pictures of the roadcut near out home as we set out!

The road cuts were less pronounced as we got further along…and more crumbly. On a botanical note – the sycamores are easy to spot this time of year.

I was so busy photographing overpasses and the bridge at Kansas City that I didn’t realize the bridge was over the Missouri River!

The Loess Bluffs (in this case roadcuts) look very different than the roadcuts further south. The loess here is from the edges of glaciers of the last ice age. Plants sometime can take root…but often sluff off and the loess is revealed again.

And then we reversed toward home.

Over the past month, the online geology course I am taking has proceeded with 4 more chapters of the textbook, an added role-playing activity on flooding, and a field trip being scheduled for early April! So far, the most thought-provoking chapter has been on water pollution. It is a topic I’ve learned about over a period of years but having a well-organized chapter tie everything I know together was almost overwhelming. The moves to reduce efforts to improve or preserve water quality at the Federal level while I was reading the chapter made the challenges we face near term and into the future even more troubling.

In the lab, there were sedimentary and metamorphic rocks to look at and then some different kinds of labs…looking a cross sections and oceanography. I skipped one of the labs because it was raining, and I decided I didn’t want to be out and about – a benefit of being a retired person. I took pictures of the rocks we looked at in the lab and made ‘flashcards’ for myself to help me learn to recognize them. Of course – the HCl test and scratch plates are also needed for identification too.

 I met my daughter for lunch after most of the lab sessions before heading back home.

Zooming – February 2025

There seems to be more going on this winter than usual. Most of the pictures I selected to represent February were taken within a 100-mile radius of home in Nixa MO…except for a few at the Josey Ranch ponds in Carrollton TX. There were some warm days…and some snow. Some of the bulbs are coming up --- growing slowing in the still frigid temperatures that keep coming. Enjoy the February slideshow!

Learning about Missouri Geology – February 2025

The geology class/lecture I am taking at Missouri State University is providing good background in general geology…but I am most interested in the geology of Missouri…trying to be more aware of the geologic features around me.

My copy of Roadside Geology to Missouri has been a good reference. On the drive from Nixa to Branson, MO, my husband’s navigation system took a scenic route (to avoid a construction area); the two-lane road was predominately downhill and followed Woods Fork over to US 65.

The road cuts are spectacular along US 65 with one of the tallest marking the margin of the Springfield Plateau…and then the Salem Plateau as we continued south. There are layers of limestone, dolomite, and shale. There were frozen ‘waterfalls’ from some of the cuts. The day was sunny, so it was easy to get pictures of the cuts as we moved past.

We stopped at the Branson Scenic Overlook downstream from the dam that created Table Rock Lake. The overlook area was the first proposed location for Table Rock Dam. There were evidently too many cracks and faults in the rocks to build it at this location. The dam was built in the 1950s and spans the White River creating the deepest lake in Missouri.

The view for the overlook shows Branson and the lake in the distance but I was more interested in the river immediately below…the bare trees and remnants of snow…ripples in the cold water.

Our field trip to the prairies near Lockwood MO (from Springfield) took us from the Springfield Plateau to the Osage Plains. It was a very cloudy day, so I took few pictures - I did notice the flattening out as we drove around farmland with parcels being maintained as prairie. There were low rolling hills. There was a significant windfarm….indicating that the wind there is reliable enough to make it worthwhile.

The final geology adventure in February was the monthly Missouri Master Naturalist meeting. The topic for the month was Missouri Geology!

Geology Course Experiences – February 2025

I have completed 3 more chapters in my online course – reading the eTextbook, working through the study questions and taking the quizzes (all part of the online book). There was a short YouTube video. The professor sent an email about another video - Hidden Fury - the New Madrid Quake Zone – which was more  substantial (although not very polished); I wondered why she did not make it part of the online course as part of the section on earthquakes. So far, the online course content seems to be almost entirely the eTextbook – very little content/value added by the professor or the university. I will finish the course and get as much as I can from the online book that I can access until next summer but probably will not take another online course from this university.

The lab course is almost better than I expected. It started out in what seemed like the traditional entry level geology lab: trays of minerals and rocks; I took a few pictures. Diorite made of quartz, plagioclase, and hornblende.

Granite made quartz, feldspar, and plagioclase. 

But the next lab (volcanoes) involved use of VR headsets or scanning a QR code to look at something on our smartphone. The lab for the next week (volcanoes again) included some more video initiated by scanning a QR code followed by a simulation of a volcano emergency with role playing. It was interesting to have the Santorini earthquakes and associated response in the news at the same time we were doing the lab. Overall, the lab is exceeding my expectations; I appreciate that the faculty is incorporating new content and delivery mechanisms into the course.

I’ve met my daughter for lunch after two of the labs…before I head back home. I showed her the imprint of the shell in the limestone near the student union before the first one; the light was better for photography.

Geology Course Experiences – January 2025

/

I started a second semester at Missouri State University in January – taking a geology course (online) and lab (in person). The semester did not start out as well as the one in the fall:

  • Unfortunately for me, the department had made the lab optional so the university’s program for people over 62 only applied to one part – make the semester considerably more expensive than the fall semester.

  • I also mistakenly signed up for an online lecture course that didn’t begin until March (it didn’t occur to me that there would be a schedule like that) so I had to make a quick adjustment to get a course that matched the lab duration.

  • The lecture part of the course (online) had a digital textbook that include study aids that was required for the course….that cost over $80. It was quite a ‘sticker shock.’

The first lab happened before I got the lecture course situation fixed, but evidently it was also before most people in the lab had attended a class too. The instructor walked us through the lab as a group, but she talked to fast that I wonder how many of the students understood it very well. Fortunately it was a topic I was familiar with.

I’ve completed the first two chapters of the textbook that have been assigned – and the associated questions/quizzes. There was one short YouTube video that was included in the assignments. I am disappointed that the professor does not include any recorded lectures for the online course; she did invite us to a similar course that she is teaching in person if we wanted to hear a lecture on particular topics…and I have gone to one.

The course and lab both reference field trips but there were none listed on the schedule for either one. I asked the lab instructor…they only knew that there hadn’t been field trips since COVID. When I emailed the professor, I was told that there would be a field trip in early April. Would it have happened without my query? Geology field trips are some of my favorites. When I was in high school, I went on several field trips with Southern Methodist University’s geology department since I had a friend whose father was a paleontologist there…and then in college I tagged along with my husband’s geology class at El Centro (community college) and University of Texas (rock roses and marine fossils and caves). In Maryland, the master naturalist training included a hike in Patapsco Valley State Park with a geologist! So – I really want at least one geology field trip from this course.

The professor also sent out a pdf with a self-guided geology tour of the campus. I did it last week; the day was too cold to do it leisurely although I did notice non-geology things along the way too.

As I walked from the lecture building toward the first stop on the tour – I made a slight detour to photograph Ozark Witch Hazel that blooms in January. The buds were open but the streamers were still curled…probably because it has been very cold during the past week.

The first stop was to see the “Carthage Stone” (limestone) façade of Carrington Hall. The foundation of the building is Missouri Red Granite from the St. Francois mountains of southeastern Missouri.

Inside the building, there is a tile floor (not a geological feature) and steps/decorative spheres of marble….a grand staircase.

I photographed tiny fossils in the polished limestone stairs of Hill Hall. The building was constructed in 1924…one of the older buildings on campus.

The Memorial Garden near the student union building has a gabbro slab (igneous like granite but with larger crystals and dark silicate minerals like plagioclase feldspar). There is also as sandstone ramp/wall along the walk to the Memorial Garden. The stones are from northwestern Arkansas and reminded me of some sandstone my grandfather used to construct some benches back in the 1960s.

There are dolomite rocks in some of the planting areas – ugly but interesting.

At the southeastern door of the student union, the slab to the right of the door is more Carthage Stone…this time with more visible fossils! The step up to the door is granite porphyry…with different crystal sizes indicating that it had 2 phases of cooling and crystallization.

It had been a cold walk but the exercise of being out and about felt good as I walked back to my car to go home. I am thinking of the walk as the first field trip of the course.

Learning about Missouri Geology – January 2025

After the field trip to the Joplin History and Mineral Museum, I set a goal for myself to learn more about Missouri Geology in 2025…hopefully make field trips throughout the state. January was a month to do some research. I already had two books (Roadside Geology of Missouri by Charles G. Spencer and Geology of Missouri State Parks by Max W. Reams and Carol A. Reams) that I was reading – already referencing to plan the coming months.

I found that my local library had several other books. They were older and out of print. Two of them could only be used in the library. Sitting in a comfy chair in the library browsing them was an hour well spent. I took pictures of the cover/title page and some of the maps/pictures/tables – realizing that this was a better option than the copier machine.

Missouri Geology by A.G. Unklesbay and Jerry D. Vineyard

Springs of Missouri by Jerry D. Vineyard and Gerald L. Feder

The third book was available for checkout so it was actually read: Gargoyle Country – The Inspiring Geology of Springfield & Greene County by Jerry D. Vineyard.

I also discovered a great overall Geology resource – a National Park Service website! It’s not specific to Missouri though.

America’s Geologic Legacy

My husband and I signed up for two birding field trips this winter that are in very different areas of the state. They will both double as geology field trips! The first one is in a prairie area of Missouri and the second is far north in the state in an are that was glaciated in the last Ice Age. I’ll take my reference books and look at roadcuts along the way (since my husband will be driving)….and geologic features while we are out of the car.
