Straight Cliffs Formation
|Usage of Geologic Unit Name:
Straight Cliffs Sandstone (UT*)
Straight Cliffs Formation (UT*)
The Straight Cliffs consist of Late Cretaceous-age sandstone and shale. This view is in Grand Staircase-Escalante Canyons National Monument near Escalante, Utah.
Plateau sedimentary province*
Not designated. Named for long line of nearly rectilinear cliffs fronting toward Escalante Valley, suggesting name "Straight Cliffs", northwest of Colorado River, Kane Co., UT. Major development from T. 41 to 37 S., R. 8 to 4 E., Kane Co., UT (Gregory and Moore, 1931).
(alphabetical): Drip Tank Member (UT*), John Henry Member (UT*), Smoky Hollow Member (UT*), Tibbet Canyon Member (UT*).
Unit Name History:
Named Straight Cliffs Sandstone (Gregory and Moore, 1931). Divided into Tibbet Canyon, Smoky Hollow, John Henry, and Drip Tank members (Peterson, 1969). Biostratigraphic dating (palynomorphs) (Nichols, 1997).
