312 million years ago, most of North America was under water. The Ancestral Rocky Mountains rose high above the sea, and braided rivers formed narrow coastal plains. The Maroon Formation, which makes up the famous Maroon Bells, and the Fountain Formation, which makes up Boulder's Flatirons, were deposited in this coastal environment.

This animation is part of a series of "paleo-satellite" views that show what Colorado might have looked like if satellite imagery was available millions of years ago.
