STILLWELL MOUNTAIN. Stillwell Mountain is fourteen miles southeast of the Persimmon Gap Ranger Station, just north of the Black Gap Wildlife Management Area in east central Brewster County (at 29°38' N, 102°57' W). At an elevation of 3,654 feet above sea level, it rises 1,450 feet above Maravillas Canyon, three miles north. Shallow, stony soils support live oak, piñon pine, juniper, and grasses. The mountain is named for Roy Stillwell, who established a ranch in the area in 1906 and was one of the first cattlemen to introduce Hereford bulls into Brewster County.
