Beneath a grassy mountain valley in central Colorado lies one of the richest and most diverse fossil deposits in the world. Up to 1700 different species have been described. A majority of those fossils are fragile, detailed compression and impression fossils of insects and plants. The largest fossils are massive, petrified Sequoia trees - up to 14 feet wide!
