Its summit, at an elevation of 4,608 feet (1,405 m) above sea level, rises 328 ft (100 m) 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.
