Stacked sequence of tepees in the basal part of the Tansill Formation.
A 1.8 m thick sandstone at the base of the exposure (at level of man)
has truncated tepee stacks in the underlying Yates Formation.
These tepees are associated with fenestral and pisolitic dolomites.
The sandstone sheets, which thin to a feather edge toward the shelf
margin, have been interpreted as sabkha deposits formed by eolian
processes during sea-level lowstands. Roadside outcrop on
Dark Canyon road approximately 2 km west of the
canyon mouth, Eddy Co., New Mexico.
