1990 Map of Temporal Pass

About this map

Growler Mountains dominate this 1990 survey, serving as a significant geological divide between the Growler Valley to the west and desert arroyos to the east. The landscape is defined by its administrative complexity, where the Cabeza Prieta National Wildlife Refuge overlaps with the Barry M Goldwater Air Force Range. This intersection of conservation and military utility is marked by the Military Reservation Boundary, showing a terrain managed for both ecological preservation and national defense. Water remains the primary shaper of the lowland topography, evidenced by the drainage patterns of Daniels Arroyo and Chico Shunie Arroyo. At the center of the range, Temporal Pass provides a noted break in the ridgeline, historically significant for movement across this arid stretch of Pima County.
