2018 Map of Alamo Spring
USGS Topo · Published 2018About this map
The United States and Mexico border bisects this remote landscape, where the northern reaches of Sonora meet the high desert of Santa Cruz County. Located within the Coronado National Forest, the terrain is defined by the sharp elevations of the Pajarito Mountains and the prominent Mojahave Ridge. This map documents a critical transborder wilderness characterized by deep drainage systems like Peña Blanca Canyon and Tonto Canyon. Given the arid environment, the presence of localized water sources is paramount; the survey identifies several man-made catchments including Border Tank, Chiladote Tank, and Coyote Tank. The namesake Alamo Spring sits near the head of Alamo Canyon, serving as a vital point of interest for those tracking historical water access in this borderland region.
