The Granite Mountains of Arizona is a mountain range in the Sonoran Desert of southern Arizona. It is located in extreme western Pima County, Arizona, bordering southeast Yuma County.
The Granite Mountains are an 18-mile (29 km) long range, trending mostly northwest-southeast; the north end of the range turns more northerly and aligns with the Aguila Mountains of Yuma County 6 miles north.
The Granite Mountain's highest point is unnamed at 2490feet. The west and south end of the mountains lie at the southeastern beginning of the San Cristobal Valley[1] flowing northwest and north to the Gila River Valley. The east side of the range borders the north-flowing Growler Valley. The southern end of the mountains are adjacent to a water divide where south-flowing drainages enter into portions of northern Sonora, Mexico.
