2018 Map of Round Mountain

About this map

The Peloncillo Mountains dominate this high-desert landscape straddling the border between Arizona and New Mexico. This 2018 survey by the U.S. Geological Survey captures a complex network of drainage systems, most notably the winding course of Railroad Wash and the extensive Coyote Wash that carve through the arid terrain. The presence of named landmarks like Round Mtn and the Bobcat Hills provides critical orientation points for hikers and researchers studying this corner of Greenlee and Hidalgo counties. Local water features such as Olney Well Draw and Horseshoe Wash highlight the ephemeral hydrologic patterns typical of the region, while Co RD a028 represents one of the few improved routes providing access through the rugged canyons, including Gillispie Canyon and Grayhorse Canyon.
