Florissant Fossil Beds National Monument, biggest source of fossilized insects anywhere.

A national monument in Teller County, Colorado, are the Florissant fossil beds. Fossilized stumps of a redwood forest litter the site, which is the most prolific source of fossilized insects anywhere in the world. Almost 35 million years ago, volcanic eruptions buried the lush valley that was once in this area. Ash petrified the redwood trees - some up to 14 feet wide - that grew here and a lake formed that became a resting place for thousands of plants and insects.
