Black Mountain is a lava capped mesa in Pima County, Arizona, that rises 1,000 feet above its base to an altitude of 3,700 feet [1]. It is a northeast trending ridge, 5,600 feet in length, located along Mission Road nine miles southwest of Tucson [1]. It is on the San Xavier Indian Reservation, 3.18 miles southwest of the Mission San Xavier del Bac [1]. The Sierrita Mountains rise to the southwest and the Santa Cruz River is about four miles to the east [1]. On top of Black Mountain are the ruins of an ancient Hohokam fortification [1]. Long stone walls, circular stone rings, petroglyphs, man-made trails, and pottery sherds can still be seen today [1].
