1971 Map of Amarilla Mountain

About this map

Mining operations and remote desert outposts characterize this portion of Brewster County as surveyed in the early 1970s. The landscape is marked by the presence of the Colquitt-Tigner Mine and several unnamed mines scattered near California Hill and Clay Mountain, reflecting the area's geological and industrial history. Travel through this arid terrain relied on a network of a Trail, Jeep Trail, and Pack Trail, connecting essential water sources like Comanche Spring, Lowes Tinaja, and Comanche Creek. Significant topographic landmarks including Amarilla Mountain, Tres Cuevas Mountain, and the Terlingua Sinkhole dominate the southern reach of the region. This survey also records Coltrin Camp and the eastern edge of Big Bend Nat Park, providing a record of the human presence and land use in this part of the Trans-Pecos before modern developments altered these remote routes.
