Gravel, sand, and silt, 30 or more feet thick, resembling recent river or lake sand plains, probably deposited in a deserted river channel, and extending over part of McAlester coal field. [Mapped (pl. 64) as Peasable sand (probably from Peaceable Creek, Hughes County, Oklahoma), but Guertie adopted in text as more appropriate name. Assigned to Quaternary(?) (Pleistocene?).]
