Whitehorse sandstone member of Woodward formation. [Introduced to replace preoccupied name "Red Bluff sandstone." Quotes Cragin's definition of "Red Bluff."] Extends from vicinity of Whitehorse Springs, Woods County, Oklahoma, southwest across the Cimarron to high divides beyond. Overlies Dog Creek shale and underlies Day Creek dolomite. [Age is Permian.]

Proposed restricting Whitehorse sandstone to upper part of the Whitehorse, and named lower part Marlow formation. This usage did not prevail, and in 1929 Sawyer named his restricted Whitehorse sandstone the Rush Springs member of Whitehorse, and called the lower part the Marlow member. [Age is Permian.]

Stated that Day Creek dolomite overlies (instead of underlies) Cloud Chief gypsum, and treated the Cloud Chief as a member of the Whitehorse. [These proposed innovations are still (ca. 1936) under investigation.]
