Earth Caching
An EarthCache is a place where people go to learn something about Earth Science, such as a particular feature or process that affects the Earth. Earthcaching is a cooperative effort between Geocaching.com and the Geological Society of America. This page is dedicated to the EarthCaches I have developed. These are designed to teach people about geologic processes.
In this EarthCache, I take the cacher to the dragon roadcut, an incredible place within one of the massive shear zones of the Grenville Province in Ontario, CA. Here the rocks are folded so much they are more like a noodle rolled on a fork. The folds resemble a serpent's head.
At this EarthCache, cachers learn about the great unconformity of the geologic time scale, the gap between the Precambrian rocks below and the Paleozoic sedimentary rocks lying on top.
Just outside Hill City, SD, in the middle of the Black Hills, lies a spectacular fold. It's so big, you can drive right by it and completely miss it. I have cachers identify the primary type of fold this is and learn a bit about how rocks are deformed by Earth processes.
Here I take cachers to eastern Tennessee to see some spectacularly folded and cleaved slates. Here, cachers will learn about the combined effects of folding and cleavage formation in low grade metamorphic rocks.
