SIERRA BLANCA. The Sierra Blanca range begins two miles north of Sierra Blanca in south central Hudspeth County and extends ten miles to the northwest (with its center at 31°15' N, 105°26' W). The range has three distinctive conical, volcanic peaks: Sierra Blanca, the highest in the range, with an elevation of 6,891 feet above sea level; Little Blanca Mountain, with an elevation of 6,178 feet; and Round Top, with an elevation of 5,732 feet. On the range clay and sandy loams support scrub brush and grasses.
