Gray Fossil Site
Discovered in 2000, this collection of fossils dates back 7 million years. Saber-toothed cats, sloths, frogs, and tapirs are some of the animal fossils on exhibit here, all of which can be seen for a mere five bucks per person. For a few dollars more, you can participate in a dig for fossils. The location is still an active dig site for paleontologists.
