This hill is noted for having the pyramidal tomb of Charles Debrille Poston at its summit. Poston lobbied President Lincoln and Congress to create the Territory of Arizona[6] and was appointed Superintendent of Indian Affairs because of his familiarity with the Native populations of the area.[7] The tomb can be accessed by a 0.6-mile (0.97 km) trail starting from the trailhead near Hunt Highway.[8]
