BLACK MESA [#2] (BREWSTER COUNTY)

BLACK MESA [#2] (Brewster County). Black Mesa, in southern Brewster County, is southwest of the Chisos Mountains and about 5½ miles north-northeast of Castolon within Big Bend National Park (at 29°13' N, 103°29' W). This mesa, which rises 2,775 feet above sea level, is composed of massive, hard, dense basaltic lava of the Chisos Formation surrounded by softer Cretaceous sedimentary rocks. It derives its name from its dark color. Mammalian tooth and bone fragments that date from the Eocene have been found in tuff deposits on the southeast corner of the mesa. The local vegetation, which includes scattered shrubs such as creosote bush and ocotillo and various semisucculents such as lechuguilla, sotol, and yucca, is characteristic of Chihuahuan Desert scrub.
