N.F. Drake applied Indian Creek to 2 units, one in Admiral formation (Permian), and the other in Strawn formation (Pennsylvanian). E.H. Sellards (Univ. Texas Bull. 3232, p. 105, 170, 173, 1933) retained the name for the Pennsylvanian unit and discarded it for the Permian unit, although the Permian name has had greater usage.

Pg. 58, pl. 27. [†Indian 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 base of Drake's Ricker bed.
