Summary:
Garley Canyon Sandstone Member of Mancos Shale reduced in stratigraphic rank as Garley Canyon Beds of Emery Sandstone Member of Mancos Shale in the northwest part of the Paradox basin, western Book Cliffs, and on the Wasatch Plateau of the Wasatch uplift. Garley Canyon is lithologically continuous with the Emery of the Wasatch plateau. Palynomorph fossils identified in NE1/4 NW1/4 sec 36, T13S, R9E, Carbon Co, UT in the Uinta basin. Of Santonian age; of middle and late Santonian age in Sanpete Valley, Sanpete Co on the Wasatch uplift, in the west; of late Santonian age in San Arroyo Canyon, Grand Co, Paradox basin, in the east.

Summary:
Formerly mapped by Hunt and others (1946) as a member of the Mancos Shale above the Blue Gate Shale Member and beneath the Masuk Shale Member of the Mancos in the Henry Mountain area, Garfield Co, UT in the Paradox basin. Name "Emery" was incorrectly used for this sandstone. Emery replaced by new name Muley Canyon Sandstone Member of Mancos in this area.
