1990 Map of Hope

About this map

Granite Wash Mountains and the Harquahala Mountains frame this arid landscape, where the Hayden-Rhodes Aqueduct cuts a definitive line across the Ran Egra S Plain. This 1990 provisional map documents the industrial and water-management infrastructure vital to the desert, including a series of flumes, siphons, and a Road on Levee tracking the aqueduct's path. The small settlement of Hope sits near the northern boundary, serving as a rare point of habitation in a region otherwise defined by resource extraction and rugged terrain. Mining activity is evident through numerous prospects and the Blackcat Mine located near Granite Wash Pass. The presence of several wells and a Check Dam highlight the critical nature of water management in this part of Mc Mullen Valley, while Bouse Wash marks the natural drainage patterns of the desert floor.
