Isn’t that tree amazing? I love how the seed for the tree somehow found it’s way into a crevice and managed to grow with its roots exposed. It’s unexpected and beautiful.
We had a great time this week exploring local geology. After a hike at the beautiful ledges, E had questions about the formation of Sharon Conglomerate. I found another park with outcroppings of the conglomerate, so we went hiking there and visited the nature center. Just as I was hoping, the nature center had a display that explained how the rock was formed.
This part of Ohio was once a river delta. As the river(s) reached the ocean and slowed, sand, small rocks, and even small shells precipitated out. Those deposits of sand and quartz pebbles eventually compressed and formed the Sharon Conglomerate. When you touch the rock it is very obviously sandstone.
In some areas we see massive sections of the conglomerate “slumping”. We learned this is usually caused by the softer shale layer underneath giving way.
When we set out on our hike last Friday, I wasn’t expecting the interest in the rock formations to emerge the way it did. The trail is actually among the boys favorite places to hike, but they hadn’t given much thought to how the rock was formed and why the crevices exist.
We had a nice time finding answers to our questions and “spending time in the field.” In addition, this made a nice extension of our previous geology studies this year. This fall, between our Yellowstone trip and FIRST Lego League research, we did a lot of study on volcanoes, thermal features and igneous rocks. I love how it is all coming together to form a really nice unit study of geology.
In other news, Learning with Boys blog turns 1 year old this week. Thank you for making this such a fun adventure. If you didn’t get a chance to check out “Signs you MIGHT be a bit nerdy”, please do and leave comments. I’ve had a great time reading the comments and nodding my head in agreement!
Hope you are having a great week!
