Fantastic colorful sedimentary patterns, Bentonite layers are seen as striations exposed in the Utah Badlands, part of the Brushy Basin shale member of the Morrison Formation. This layer was formed during Jurassic times when mud, silt, fine sand, and volcanic ash were deposited in swamps and lakes. Aerial photograph.

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.

Devil's Postpile, a spectacular example of columnar basalt. Once molten and under great pressure underground, the lava that makes up Devil's Postpile cooled evenly and slowly, contracting and fracturing into polygonal-sided columns. The age of the formation is estimated between 100 and 700 thousand years old. Sometime after the basalt columns formed, a glacier passed over the formation, cutting and polishing the tops of the columns. The columns have from three to seven sides, varying because of differences in how quickly portions of the lava cooled.
