NEEDLE PEAK. Needle Peak is in southeastern Presidio County (at 29°26' N, 103°49' W) a mile west of the Brewster county line. Its summit, at an elevation of 4,608 feet above sea level, rises 328 feet over the Lower Shutup, a canyon that runs along its eastern edge. Needle Peak is a Tertiary intrusion and stands within the Solitario, a circular domal uplift with a nine-mile diameter and a prominent limestone rim. The area is desert mountain terrain of basalt deposits. The vegetation consists primarily of sparse grasses, cacti, desert shrubs, and scrub brush. Needle Peak was named for its configuration.
