About

Florissant Fossil Beds Information

Beneath a grassy mountain valley in central Colorado lies one of the richest and most diverse fossil deposits in the world, including petrified Sequoia trees.

Up to 1700 different species have been described at this monument. 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!
