Approximately 100 m-thick section of interstratified red siltstone and gray, massive, bedded
evaporite of the Seven Rivers Formation. Note extensive gullying of the soluble evaporite
and presence of capping layer of dolomicrite (Azotea Dolomite) which has preserved
outcrop from erosion. Outcrop in Seven Rivers embayment on New Mexico Highway
137, about 10 km north of the intersection with Dark Canyon road, Eddy Co, NM.
