Organ Pipe Cactus National Monument dominates this desert landscape in southern Arizona, centered on the stark transition between the Valley of the Ajo and the rising elevations of the Puerto Blanco Mountains. This 2021 survey shows a terrain defined by seasonal drainage patterns, where Alamo Wash and Cherioni Wash snake through the arid lowlands. High points such as Tillotson Peak and Pinkley Peak provide significant topographic relief, marking the southern reaches of the monument boundary.
