About this map

The Chiricahua National Forest and Chiricahua Wilderness define the western portion of this 1980s landscape, where the high terrain of the Chiricahua Mountains meets the arid basin floor. The boundary between Arizona and New Mexico bisects the quadrangle, with the border crossing noted by Mon 35. This desert environment is shaped by water management and resource extraction, evidenced by several wells, a Check Dam, and a Mine Shaft located east of the San Simon River.

The survey captures a transition in utility and ranching infrastructure, showing a prominent Pipeline running northwest to southeast alongside a Levee. Features like the Corral and Substa near the riverbank indicate a landscape utilized for both grazing and energy transit. Cave Creek and Hackett Canyon drain the eastern slopes, leading toward the ephemeral riverbed that serves as the primary drainage for this interstate border region.
