Summary:
Pg. 315. †Oak Creek formation. Name Oak Creek formation, proposed by Troxell for these deposits [Pliocene] in South Dakota, is preoccupied. Relationship of these deposits recently named Valentine and Ash Hollow formations of Nebraska is not clear (time range of both being indicated in South Dakota without corresponding changes of lithology). Hence, it is inadvisable to attempt to extend these formations into this area [Big Spring Canyon]. Therefore these beds [Oak Creek] are referred to Ogallala group without formal formational designation.
