Pg. 141-142, pls. 3, 27, and map. Asher formation. Typical red beds. Basal 30 feet consists of a series of coarse, red and brownish-red sandstones that cap north bluff of Canadian River from bridge south of Asher to northern edge of Stonewall quadrangle. Contains no arkosic material, but arkose is characteristic of underlying Pontotoc terrane [group]. The portion of formation present in northwest corner of quadrangle is 250 feet thick. No upper limit is here defined. No fossils found, but upon evidence afforded by color and position in section is referred to lower Permian. Next younger formation is Guertie sand, of Pleistocene age. Report includes geologic map.
Named from development at and west of Asher, Pottawatomie Co., central southern OK.
