About this map

The Peloncillo Mountains dominate this high-desert landscape along the intersection of four counties and two states. The survey captures a complex network of canyons and peaks where the Arizona-New Mexico state line meets the junction of Cochise, Graham, Greenlee, and Hidalgo counties. Distinctive landforms such as Engine Mtn and Horsefoot Mtn rise above the drainage systems of Horseshoe Wash and Wood Canyon.

Hydrological features like Indian Spring, Rockhouse Spring, and the seasonally wet Playas de Los Pinos suggest the critical importance of water sources in this arid environment. Transportation through the area is limited to primitive routes like High Lonesome Rd and Co RD a021, highlighting the isolation of the terrain. The map provides a detailed record of the physical geography of this borderland region, from the depths of Little Doubtful Canyon to the summits of the Peloncillo range.
