2021 Map of East Pass

About this map

Crater Range dominates the northern horizon of this landscape, where the high-elevation passage at East Pass provides a natural corridor through the volcanic terrain. To the south, the Growler Mountains and Childs Mtn rise sharply from the desert floor, framing the broad expanse of Childs Valley. The map reveals a land defined by its drainage patterns, with the ephemeral Tenmile Wash cutting diagonally across the central flats toward the southeast. This 2021 survey also captures the precise administrative boundary where Maricopa County meets Pima County, a line that bisects the southern reaches near Daniels Arroyo. The lack of established settlements or improved roads underscores the arid, protected nature of this Sonoran environment, where travel follows the natural contours of the mountain passes and dry watercourses.
