Experience the Prehistory of Colorado
Beneath a grassy mountain valley in central Colorado lies one of the richest and most diverse fossil deposits in the world. Petrified redwood stumps up to 14 feet wide and thousands of detailed fossils of insects and plants reveal the story of a very different, prehistoric Colorado.
Did You Know?
In 1922, Fossil Cycad National Monument, in South Dakota, was established as the third NPS area to preserve fossils, however by the mid 1930s all the fossils visible at the surface had been removed, leaving nothing for visitors to see. As a result, congress removed Fossil Cycad National Monument from the National Park System in 1957.
