The Tinajas Altas Mountains dominate this borderland landscape, where the jagged peaks separate the Lechuguilla Desert to the east from the Yuma Desert to the west. A critical passage through the range is visible at Tinajas Altas Pass, a name that hints at the vital water source of Tinajas Altas located nearby. These natural tanks were historically essential for travelers crossing this arid corridor between the desert plains.
