1982 Map of Tinajas Altas

USGS Topo · Published 1982

About this map

The International Boundary between the United States and Mexico cuts a sharp diagonal through the arid landscape of the Yuma Desert in this military control sheet. Surveyed by the Corps of Engineers and based on earlier control from the International Boundary Commission, the map focuses on the stark topography of the Tinajas Mountains and the Sierra de la Lechuguilla. A series of numbered boundary markers, such as Mon. 199 and Mon. 190, track the political divide across the Sand Hills. Notable for desert travelers, the Tinajas Altas region highlights critical water sources or Tinajas found within the mountains. Primitive roads and trails connect this remote borderland to distant points, with routes marked From Yuma, To Gila River, and To Tule Wells, reflecting the region's historical reliance on established desert tracks.
