2022 Map of San Antonio Pass

About this map

San Antonio Pass dominates the high-altitude topography of this High Desert landscape, where the peaks of Buck Mtn give way to a network of deeply etched drainages. This recent U.S. Geological Survey study details the drainage systems of H O Canyon, Wood Canyon, and Merrill Canyon as they descend from the highland. Human activity is defined by long-established ranching corridors and vital water sources like El Muerto Springs, which have historically supported livestock in this arid environment. The southern portion of the map identifies the jurisdictional boundary between Jeff Davis and Presidio Counties, while a sparse network of roads, including Kelly Ranch Rd and Gearhart Ranch Rd, navigate the canyons toward more secluded features like Bat Cave Canyon.
