Fantastic colorful sedimentary patterns of Bentonite layers, seen as striations exposed in the Utah Badlands. The Bentonite Hills are composed of the Brushy Basin shale member of the Morrison Formation formed during Jurassic times when mud, silt, fine sand, and volcanic ash were deposited in swamps and lakes into layers, now revealed through erosion. Aerial photograph.
