Summary:

Is one of five divisions of the Upper Permian Rustler formation. Upper contact revised in that Culebra underlies the newly named Tamarisk member of Rustler. Overlies in the subsurface the unnamed lower part of the Rustler. Exposures of Culebra are deformed by solution collapse. Mapped (geologic map) in three small exposures east of Salt Lake in southwest part of quad., Eddy Co., NM in the Permian basin where it is described as a gray, thin bedded to massive silty dolomite with spherical plugs 1 to 1 0 mm in diameter. Member is 30 ft thick. Is the oldest unit mapped in quad. Stratigraphic table. Drillhole cuttings described.
