GRAYTOP. Graytop is a lone conical peak on the northeast side of Nine Point Mesa sixty-five miles south of Alpine in south central Brewster County (at 29°39' N, 103°25' W). It reaches an elevation of 4,348 feet above sea level and rises some 400 feet above the surrounding terrain. The name probably refers to the grayish cast of the stone that forms the cone, a contrast to the reddish rock of Nine Point Mesa towering behind it. Graytop lies in what was once predominantly a grassland ecosystem, but intense grazing from the commercial livestock industry virtually destroyed the grasslands, leaving only remnants intact near the peak. In 1990 the area around Graytop was dominated by Chihuahuan Desert scrub, including lechuguilla, ocotillo, sotol, and creosote bush.
