Florissant Fossil Beds National Monument, Colorado

14-foot-wide stumps of petrified redwoods and thousands of insect and plant fossils await you in Florissant Fossil Beds National Monument. That’s right, the ancient world is more than just mammoths and dinosaurs. The little organisms matter, too, and you can check them out at the visitor center and on the fossil trails. In the summertime, you can check out the on-site yurt that serves as a fossil lab.
