About this map

The Peloncillo Mountains dominate this high-desert landscape in southeastern Arizona, straddling the border between Greenlee and Graham counties. This terrain is defined by volcanic features and significant relief, punctuated by high points such as Rhyolite Peak, Thumb Butte, and Ash Peak. The drainage patterns here are complex, with seasonal watercourses like Tollgate Wash and Shoat Tank Wash carving deep into the earth.

Historically, the distribution of water sources is the primary indicator of land use in this arid region. Numerous tanks and springs, such as Harris Camp Spring and Yellowstone Tank, are vital landmarks for livestock management and survival in the high desert. The map also reveals names tied to local topography and ranching history, including Jackpot Mesa and Slick-Rock Basin, illustrating how the early settlers and surveyors identified this challenging environment.
