View of bedding plane of Lamar Limestone (the youngest Guadalupian carbonate in the Delaware Basin).
Note abundance of evaporite crystal casts —these indicate hypersaline conditions in the basin center
either during or immediately following Lamar sedimentation. This is also supported by paleoecological
studies on the unit. Roadside outcrop along U.S. Highway 62-180 approximately 1 km north of
intersection with road to McKittrick Canyon, Culberson Co., Texas. Coin is 1.8 cm in diameter.
