Echo Canyon, Utah: impressive cliffs of river gravel shed off big mountains in the Cretaceous Period

The towering, scenic cliffs of Echo Canyon along I-80 between Park City, UT and Evanston, WY record a fascinating geologic history of towering mountains and fast-flowing rivers. Join geology professor Shawn Willsey as he investigates the Sevier Orogeny, a major mountain building event in western North America during the Cretaceous Period, about 80 million years ago. Learn how these highlands (now eroded) formed and how the high energy streams that drained the mountains shed large loads of sediment eastward.
