South Mountain seen from Laveen, Arizona

The South Mountains, known locally as simply South Mountain, is a mountain range in central Arizona in south Phoenix, Arizona. It is on public land managed by the city of Phoenix as South Mountain Park. Geologically, the South Mountains are thought to be a metamorphic core complex: evidence of movement of the North America tectonic plates from southwest to northeast and northeast to southwest, pushing up a series of mountain ranges including the South Mountains, which are some of the few remaining ones, the other ones having been covered up by silt (forming the current Phoenix metro area, which looks flat like a lake around mountains that kind of stick up over it like islands). The underlying mountains are in the same orientation as the South Mountains, about one km high, and about one km apart from peak to peak, perhaps about 15 of them underneath the land.

The South Mountain Preserve is part of the Phoenix Parks System and is the largest municipal park in the world. The preserve features recreational facilities such as ramadas, hiking and mountain biking trails, and equestrian facilities.



The major peaks of the South Mountains are (W to E):

  • Maricopa Peak
  • Goat Hill
  • Mount Suppoa (South Mountain, TV Tower Peak), highest point in the mountains at 2690 ft (820 m). Contains numerous radio and television transmitters serving the Phoenix area, especially those of the major network-affiliated stations.


  • Dobbins Lookout is the highest point accessible by trail at 2,330 feet (710 meters).
  • Alta Ridge is the ridge on the eastern end of Maricopa peak.
  • Telegraph Pass is the gap between South Mountain to the east and Goat Hill to the West.
  • Fat Man's Pass is located on the National Trail and is a rock formation.
  • Mystery Castle is in the foothills on the north side and was built from odd materials and trash around 1930 as a private residence.
  • There are approximately 20 communications towers on the peak of South Mountain.
  • There are ruins of both ancient Indian and more contemporary origin, and there are many petroglyphs carved into the desert varnish on the rocks.

Geography and Ecology

A spur plateau of the Salt River Mountains was described by an early survey of the area as the dividing feature of the Salt River valley.[1]

There are a variety of flora and fauna within the Salt River Mountains. One of the notable tree species here is the Elephant Tree, Bursera microphylla.[2]
