Last week I spent a morning hiking with 4th graders at Howard County Conservancy’s Belmont location. The theme for the hike was how the land has changed from it was all a forest 300+ years ago…to the way it is today with emphasis on the impact of our development of farms and factories…streets and homes.
I arrived early to help with set up. I carried a bag with materials for the terrain model to the table mid-way along the hike and then carried the other bag into the forest for the students to compare aerial photos of the Belmont area. I took some pictures since I knew once the students arrived I wouldn’t have time for more – I am totally focused on the students while we hike. Some areas in the forest have deep leaf litter and would soak up a lot of water before the water would run off…and right now there are some leaves that are still colorful too.
Coming out of the forest I took a picture of the Belmont cemetery and the row of white pines. I took my hiking groups to the side of the cemetery and talked about the ground penetrating radar that was used a few years ago finding graves under the ground within the cemetery even where there are no markers and also where we were standing outside the fence (lot’s of fun to point out on a Halloween hike) but the conversation also included the idea of shifting of sediment and deterioration of grave markers that might have been made of wood. The pine needles that have accumulated over the years under the pines make the ground feel spongy; that surprised some of the students….and that area would soak up a lot of water just as the leaf litter does – like a sponge.
There was a terrain model that we poured blue liquid over to represent the normal river level…then more blue liquid to be a minor flood (houses nearest the river wet)…up to the level representing the 1868 flood which washed away Elkridge Landing and parts of Ellicott City. The mills never recovered, and towns ceased to exist. The students were surprised to learn that the flood experienced by Ellicott City in 2018 was not that much below 1868 and it was higher than the flood caused by Hurricane Agnes (1972) in Ellicott City.
Overall – it was a great day for a fall hike with 4th graders!
