2019 Map of Amarilla Mountain

About this map

Amarilla Mtn and Tres Cuevas Mtn dominate this portion of Brewster County, where the high desert terrain transitions into the northern reaches of Big Bend National Park. The landscape is a complex network of dry canyons and seasonal watercourses, including Croesus Canyon and Well Cr, which navigate between prominent elevations like Black Mesa and Sierra de Cal. Human activity is concentrated along the arterial Ranch Rd 170, supporting the Lajitas International Airport and a series of recreational paths such as the Singlespeed Trail. Evidence of the region's geological and industrial history is scattered throughout, from the Terlingua Sinkhole to the N Lone Star Mine, illustrating the persistent effort to extract resources from this demanding environment near Comanche Spring.
