Next, I stopped at Agate Fossil Beds National Monument Visitor Center and Museum in Sioux County NE. I spend some time inside looking at all the artifacts on display and watching a film about the fossil beds and the people that discovered them. Afterwards I hiked the Daemonelix trail. Half way up the cliff face they discovered a series of vertical spiral shapes. The locals called them Devil Corkscrews but they are actually burrows of ancient beavers leading down to nesting areas underground. They are approximately 20 to 23 million years old, dating back to the Miocene epoch of the Neogene period. I completed 3 Earthcaches before continuing on north to the Toadstool Geological Park, which I will tell you about in my next post.
Thanks for visiting
