History of investigation
The unit was first identified in the subsurface at the Yates oil field of west Texas. It was first traced to surface outcrops in the Carlsbad, New Mexico area in 1938 and assigned as a member of the (now abandoned) Whitehorse Formation. Dickey raised the unit to formation rank in 1940, when the Whitehorse was raised to group rank. The unit was reassigned to the Artesia Group in 1962.
