Summary:
Named presumably for Pima Co., AZ. No type locality designated. A "buff, hard sandstone with inclusions of the Bolsa quartzite in places." This sandstone, only 4 ft thick, "has been traced more than 60 mi from the Whetstone Mountains" in Cochise Co., in the Pedregosa basin to the Picacho de Calera Hills, Pima Co., in the Basin-and-Range province. [He no doubt meant "correlated" rather than "traced".] Overlies Bolsa quartzite. Overlain by Cochise formation. Is of Middle Cambrian age.
