location
Mount Evans. Arapaho National Forest (Clear Creek County, Colorado, US)notes This low-relief pediment formed during late Eocene time across much of the Front Range of the Rocky Mountains. The development of the pediment followed the Laramide period of mountain-building, which ended about 40 million years ago. Regional uplift since then raised the pediment thousands of feet above the plains to the east and subjected it to extensive incision. Widespread remnants of the once-continuous surface serve as markers for later uplift and deformation of the Rockies. This view is from Mount Evans, looking to the south along the crest of the Front Range. The surface seen here is at an elevation of about 11,500-12,000 ft.keywords: geology, earth science, geomorphology, Eocene, Tertiary, erosion, pediment, uplift
