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.

Geology Course Experiences – March 2025

/

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.

Missouri Giant Traveling Map

/

Doing a program for 7-13 years old students with the 17 feet x 21 feet Missouri Giant Traveling Map at a nearby county library was a learning experience for me as a Master Naturalist (and my partners too). For one session we had 18 students and the other one 4. The groups were enthusiastic to be out and about after a snowstorm had kept them inside for a few days. They enjoyed taking their shoes off and walking around on the map…so much that they sometimes started sliding on the plastic a little too much.

That age group has had some great outdoor experiences in the state – but they don’t necessarily know where they went unless it is associated with a city. Fortunately - one of the fathers took off his shoes and stepped on the map to show his daughter where the river they had floated down was on the map.

The students also were able to look at rivers in Missouri that flow into the Mississippi River directly…ones that flow into the Missouri River and then the Mississippi…and those that flow south into Arkansas and the rivers there before eventually flowing into the Mississippi.

We noted the grayish areas on the map…where the terrain is very hilly…and other areas that were not. I suggested that they look at roadcuts when they are out and about in the state (that it is a safe thing to do since they are not driving!)…and notice that not all of the layers of rock are horizonal…and think about how the layers can become the way they are.

We have 3 more topics we are presenting in upcoming library sessions and we learned: to have a better idea of how many people we expect and be more assertive when some of the students are disruptive. We also realized that it was fortunate that our subsequent sessions are more hands-on active rather than simply walking around and looking. We’ll get better with each one!

Different in 2025

/

What am I anticipating being different in 2025?

It is a better thought process for me than making a list of resolutions…even though to make some of the ‘anticipations’ become reality it will take some intentional action on my part which might be very much like the focus a resolution can have. But I am noticing that what I have on my list this year are things that have been available in some form to me before; I am simply making the decision to follow through…and enjoy the ride.

Last year I enjoyed the Missouri Master Naturalist (MMN) training and in 2025 I am going to explore the opportunities associated with being an MMN. I’ll be organizing the monthly programs for the chapter and ramping up my volunteering. At the end of 2024 it appeared that 20 hours of volunteering per month would be feasible…and I might discover that I can do more during some months of the year.

My husband has pointed out that the local Audubon Society chapter has great field trips and we are already planning to go to 2 in early 2025….and more of those will probably become our norm.

I initiated some Missouri geology themed day trips in December (1st one was to the Joplin History and Mineral Museum and Grand Falls) and want to do more in 2025. We’re planning to go to Loess Bluffs National Wildlife Refuge in February for birding….but there will be geology there too (it in the part of the state that was glaciated)! Maybe I will make a day trip to the Ed Clark Museum of Missouri Geology in Rolla in January. I’ve always wanted to take a basic geology class but never could fit it into my schedule back when I was in college…so I am registering for one during the 2025 spring semester at Missouri State University; maybe they will have a field trip or two.

I hope I can finally renew my friendship with a childhood friend (we’ve been exchanging Christmas cards for years but haven’t seen each other since we were in our teens). We have been communicating via text over the past year but then events in our families made it challenging to reconnect in person. Maybe it will happen in 2025.

The physical therapy I am getting now is beginning to yield positive results and I am anticipating that a lot of the activities I want to do are going to be easier for me physically…so I am very motivated to do what they tell me and continue a routine of exercises that will sustain the improvement.

I am looking forward to the differences from 2024 that I am anticipating!

Joplin History and Mineral Museum

/

My daughter and I picked a sunny day before Christmas for a ‘field trip’ to the Joplin History and Mineral Museum. It was the first of my planned geology field trips in the coming months; as soon as I realized that the Missouri Master Naturalist training did not include a geology segment, I started thinking about how I could educate myself and field trips are probably my favorite options.

Joplin has a lead-mining history so many of the minerals on display include galena (black cubes usually). There were big chunks of rock and crystals. The smaller items were in glass enclosed cases around the edge of the room…large pieces on stands in the center. The labeling was well-done with numbers by the specimen and then signage nearby with the information about the specimen.

On the landing of the stairs was a case of Missouri fossils and ancient Native American artifacts. I liked the poster of different types of arrowheads.

The history side of the museum included a cookie cutter museum. I was intrigued by a circular one from Mexico with multiple shapes inside….very little dough to roll out again. They used a set of state shaped cookie cutters as part of the transition to the Route 66 part of the museum.

There was a room with models of circuses and a Victorian doll house. The doll house has plastic over the open side…but it looked like the model dog had run around and knocked over things (the Christmas tree on its side…a book and lamp pushed off a table); I told the person at the desk and we both chuckled. The doll house has had the plastic barrier on it for a long time, but the house has been moved recently and the jostling might have been enough to knock over the items.

There was also a display of the very destructive 2011 tornado in Joplin which tried to show how destructive tornados can be. The twisted muffin tin was the first item that caught and held my attention. Not far away there was a tree that had been splintered. I read more about the event when I got home and discovered that the tornado’s upheaval of the soils along its route caused re-contamination from lead mining remnants in southern Joplin…so the natural disaster recovery had a linkage to the city’s lead mining history too.

Outside there was a bench painted with wildflowers and towers of Missouri rocks. There was a metal sculpture that was interesting too.

My daughter and I had a pleasant lunch at Los Primos Mexican Grill in Joplin….sharing guacamole at the beginning and flan at the end of the meal.

Our next stop was Grand Falls – not far off I-44 west of Joplin. The lower falls is Grand Falls Chert, at 20 to 30 foot think bed of pure chert in an area otherwise dominated by limestone. The chert is extremely resistant to erosion because it is made of silica. The falls is the state’s broadest continuous flowing waterfall.

On the way home toward Springfield, my daughter looked closely at the road cut at mile marker 27.0 as I drove by and saw that the Chesapeake Fault Zone displaces the beds by a few feet toward the western end of road cut on the north side of I-44.

Both the Grand Falls and Chesapeake Fault Zone geology minutes were prompted by a few paragraphs from Roadside Geology of Missouri by Charles G. Spencer.

Overall – a good first ‘geology’ field trip.

How do countries measure immigration, and how accurate is this data? - Three types of migrants who don’t have a legal immigration status. First, those who cross borders without the right legal permissions. Second, those who enter a country legally but stay after their visa or permission expires. Third, some migrants have legal permission to stay but work in violation of employment restrictions. Most high-income nations have a small minority of irregular immigrants in their immigrant population; the exception is the United States which estimates 22% of their immigrants are irregular.

Riding The Rails on Amtrak's Cardinal Line Through New River Gorge – Maybe a relaxing way to see the National Park and Preserve…thinking about next fall.

Mother Tiger Teaching Cub How to Fight Wins Nature’s Best Photo Awards – Great pictures….but Patricia Homonylo’s video is the most thought provoking….the one that is a call to action.

Geologists rewrite textbooks with new insights from the bottom of the Grand Canyon - From the Tonto Group's 500-meter-thick strata, we're learning about sea-level rise and the effects of catastrophic tropical storms -- probably more powerful than today's devastating hurricanes -- during a period of very hot temperatures when the Earth was ice-free.

Quantifying How Urban Trees Cool Cities - The authors of a new study estimate that the city of Baltimore could reduce land surface temperatures by 0.23°C if they increased tree canopy by 1%. To achieve 1.5°C of cooling, they would need to increase tree canopy cover by 6.39%.

Ten Little Celebrations – October 2024

/

The temperatures were more pleasant in October….I enjoyed the outdoor field trips and classes a lot more.

Pleasant temperature to walk around the Missouri campus during class. We were outdoors longer but it was easy compared to short hikes around campus in August and September!

Field trip to a healthy stream and woodland. Celebrating the water quality and the native species (not overcome by invasives)!

Cut down a Japanese barberry and burned most of it. Celebrated one more non-native (that is sometimes invasive) being gone from my yard.

Geology field trip plans. I celebrated that enough of my Missouri Master Naturalist classmates and chapter are interested in geology field trips to make them a likely late fall/early winter activity.

Getting seeds planted. I got buckeye, Hopi sunflower, common milkweed, and persimmon seeds during the second week of October….and celebrated when I got them planted. Some must go through the cold temps of winter to sprout in the spring.

Volunteering at a fair for homeschoolers…talking about Monarch butterflies. I celebrated by first gig as a Missouri Master Naturalist…and that my iPad-based slideshow of Monarch butterfly pictures was well received.

Owl Pellet. I vaguely remember that I had dissected an owl pellet in some previous training…but I celebrated that I did a more thorough job this time… and found a complete rodent skull…and the backbone…lots of ribs.

First solo Missouri Master Naturalist volunteer gig. I celebrated that the two days spent doing an after-school program with a local school for gift students was positive for them…and for me!

Whataburger. Sometimes I just want to splurge. On the way back from my Dallas trip, I stopped for a Whataburger…celebrated that it tasted just as I remembered - although I won’t do it very often.

Successfully completed my Missouri Master Naturalist training. Hurray! I am celebrating what I learned and that I now have more time to volunteer!

Missouri Master Naturalist Training – Week 8

/

Week 7 of Missouri Master Naturalist consisted of two sessions: a lecture on Fungi that was part of the monthly chapter meeting and two lectures in our regular class: Snakes of Missouri and Endangered Species and Conservation. I took notes during all three! I particularly enjoyed the photographs in the fungi lecture, the snake experiences from a place we had visited for a field trip, and the example used for talking about endangered species (freshwater mussels). I still have a lot of materials from the Missouri Department of Conservation that were on the handout table to browse through from the regular class: salamanders, snakes, mushrooms, lizards, crayfish, toads and frogs, caves and karst, Missouri fishes.

During week 8, I also took action to learn more about Missouri geology on my own since it is not a topic that was covered in the training….starting with two books: Roadside Geology of Missouri by Charles G. Spencer and Geology of Missouri State Parks by Max W. Reams and Carol A. Reams. The second book is the most current – copyrighted in 2022; about 25% of the books is an overview of Missouri geology and then there are sections for state parks by physiographic region. I’ll start with the state parks since it seems safer than stopping at road cuts…although I might keep the Roadside Geology in the car for when my husband is driving, and I can observe as we are on the road.

Next week is graduation week! The time has flown by. I have an evaluation form that I am completing this weekend.

Gleanings of the Week Ending October 12, 2024

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.

Who Was Buried in Spain’s Megalithic Necropolis of Panoría? - More women than men were buried in Panoria, where human remains were interred in collective burials between 4,100 and 5,600 years ago.

On Navajo Lands, Ancient Ways Are Restoring the Parched Earth - Traditional rock and stick structures, similar to those used by Native peoples long before Europeans arrived on the continent, are not only delivering water to crops they are also restoring the watershed and those of neighbors, helping to sequester carbon, and reviving this high-desert ecosystem…. an opportunity to begin developing localized food economies.

Megadiverse flowering plant family on isolated islands – A high number of evolutionary events -- occurred in the aster family (daisies, sunflowers, and asters) within relatively short time periods on many islands worldwide.

Why is Mount Everest so big? New research highlights a rogue river – but deeper forces are at work - Everest is around 250m taller than the other great peaks of the Himalayas. It is also growing by about 2mm each year – roughly twice as fast as it has been growing on average over the long term. The Arun river’s course changed around 90,000 years ago, eroding away rock that was weighing Everest down – and the mountain has bounced up in response, by somewhere between 15 and 50m. However, the “fundamental cause” of the peak’s size is the tectonic processes that create mountains.

Researchers Grow an Extinct Plant From a 1,000-Year-Old Seed - Israeli researchers have grown the seed of a previously unknown species of flowering plant into a mature tree. In the late 1980s, archaeologists excavating caves in the northern Judean desert discovered a well-preserved but mysterious seed that had likely been carried there by animals. The seed could be dated to between 993 C.E. and 1202 C.E. and that it was a unique member of the commiphora family, a flowering plant known for its aromatic resins. Chemical analysis of the leaves shows an abundance of medical properties in the leaves, and its lack of fragrance matches descriptions of the tsori in the Bible.

Rare and Elusive Australian Bird, Once Thought Extinct for 100 Years, Discovered by Indigenous Rangers and Scientists – Night parrots are generally difficult to detect—a fact that has been long recorded in Indigenous culture. The elusive species creates tunnels and nests in dense spinifex bushes and emerges at night to forage for seeds.

5 things to know from this week’s big report on cannabis - A new report from the National Academies of Sciences, Engineering and Medicine finds the disconnect between the states and the federal government is leading to fragmented policies, and risks to the public. 5 takeaways:

  1. People consume cannabis more regularly than alcohol in the U.S.

  2. Weed and vapes can be super potent and that’s not always disclosed

  3. You can get psychoactive hemp products even in states where cannabis is illegal

  4. Research on cannabis is stifled

  5. Cannabis can be dangerous, but people hear more about its benefits than risks

Biodiversity Becoming a Top Priority - A survey of 300 landscape architects, designers, and landscape architecture educators in the U.S. found that 96 percent of landscape architects are familiar with the impacts of the biodiversity crisis. 45 percent have made biodiversity conservation a top priority of their practice and another 41 percent consider biodiversity as part of their organization’s environmental ethos.

Medical imaging breakthrough could transform cancer and arthritis diagnosis - A new hand-held scanner developed by University College London researchers can generate highly detailed 3D photoacoustic images in just seconds, paving the way for their use in a clinical setting for the first time and offering the potential for earlier disease diagnosis (cancer, cardiovascular disease, and arthritis). What a boon if this could become the new standard…avoiding waiting for an imaging appointment, having to sit still for a long time, and higher cost of current technology!

Incredible Winners of the 2024 Natural Landscape Photography Awards – Couldn’t resist this collection of beautiful images to finish off the gleanings for this week.
