Sierra Pinta

The Sierra Pinta mountain range is a narrow, remote block trending northwest-southeast, spanning approximately 22 miles (35 km) in length, located in the arid northwestern Sonoran Desert of southwestern Arizona. Its name, derived from Spanish for "Painted Mountains," refers to its striking multicolored hues during sunrise and sunset. The range is situated near the US-Mexico border, north of the Pinacate Reserve in northern Sonora, Mexico.

Key peaks include Point of the Pintas at 1,272 feet (388 m), Isla Pinta at 2,008 feet (612 m), and the highest peak, Pinta Benchmark, at 2,950 feet (899 m). The Sierra Pintas are located near the southern end of the Mohawk Valley, bordering the Bryan Mountains to the east and the Tule Desert to the west. Southward lies the El Pinacate y Gran Desierto de Altar, an active volcanic field.

The range is part of the Cabeza Prieta National Wildlife Refuge. Access is limited; nearby roads include the Christmas Pass Road, which connects to the remote El Camino del Diablo (Devil's Highway) near the US-Mexico border. The region is characterized by its harsh desert environment and sparse human activity due to its remoteness.

Notable geographical features surrounding the Sierra Pintas include the Mohawk Valley to the east, the Tule Desert to the west, and the El Pinacate Reserve to the south in Mexico. The range's ecology and isolation make it a significant area for conservation and exploration.
