1988 Map of Diaz Peak

About this map

Organ Pipe Cactus National Monument dominates this desert landscape, where the dramatic elevation changes of the Ajo Range create a sharp contrast with the expansive Sonoyta Valley to the south. This 1988 provisional edition captures a transition in the region's topography, marking significant high points like Diaz Peak and the distinctive Diaz Spire. The map illustrates a remote wilderness managed for conservation, yet it remains a place of cultural convergence as the monument's eastern boundary meets the Papago Indian Reservation.
