About this map

Ali Chuk and Ali Ak Chin are the primary settlements in this arid landscape along the international boundary between the United States and Mexico. The terrain is defined by the prominent Ajo Range and the Sierra de Santa Rosa in the west, giving way to the broad Ali Chuk Valley and La Quituni Valley to the east. A network of ephemeral waterways, including Ali Chuk Wash, Pia Oik Wash, and Slover Shuatak Wash, converge toward Menagers Lake, a notable hydrologic feature in this desert environment.

The western portion of the map is protected within the Organ Pipe Cactus National Monument, highlighting the conservation of this unique ecological zone. The inclusion of the Sierra de la Nariz south of the border provides geographical context for the cross-border landscape. Local travel is facilitated by Rte 1 Bia, which connects the small desert communities and follows the natural contours of the valley floors between distinctive landmarks like Slit Rock and Cerrito de la Angostura.
