Summary:

Pg. 58, pl. 27. [†Cottonwood Creek bed of Strawn formation not used by the USGS; a local term considered obsolete. See also entry under Strawn.] Drake (1893) separated rocks of Strawn group [division] into 20 units of alternating sandstone and shale beds. He gave local names to these units, or "beds" as he termed them, and numbered them from bottom to top, 4 to 23. Only Drake's name for upper unit, the Ricker, is in common use today, and that name has been restricted to the base of Drake's Ricker bed.
