Water divide mountain range
Ajo Peak as part of the Little Ajo Mountains forms part of a water divide, and splits into three directions-(a "Triple Divide"), part of two drainages. The Growler Valley and the San Cristobal Wash Drainage go south-west-north from the Ajo Peaks; also northwest; these two directions skirt the Little Ajo and Growler Mountain ranges. The second drainage goes from the northeast, is northwest trending through the east perimeter of the Childs Valley and forms the headwaters to the Tenmile Wash Drainage. Both drainages disappear into the ground before reaching the Gila River Valley.
