2018 Map of Tillotson Peak

About this map

Organ Pipe Cactus National Monument dominates this desert landscape in southern Arizona, where the arid terrain is defined by dramatic peaks and seasonal drainages. Rising from the western edge of the Valley of the Ajo, prominent summits such as Tillotson Peak and Pinkley Peak provide significant navigational landmarks for the region. The map tracks the drainage patterns of Alamo Wash and Cherioni Wash, which carve through the basin floor between the rugged outcrops of Puerto Blanco Mountain. Human passage through this protected wilderness is limited to established corridors like Puerto Blanco Dr and the Co Road Trail, illustrating the balance between conservation and access in this borderlands environment. The cartography reflects a modern view of the Sonoran Desert's natural topography, emphasizing the isolation and elevation changes of the Puerto Blanco range.
