About this map

Lisbon Valley sits at the heart of this mid-century survey, a landscape defined by an intricate network of drainages and mesas crossing the Utah Colorado border. The map reveals a post-war ranching and resource-extraction economy, marked by the presence of numerous shafts, tunnels, and prospects throughout the canyons. Named ranching homesteads like Woods Ranch and Patterson Ranch are situated near the Three Step Hill area, while the West Summit School provides evidence of a sparse but established rural community in the southwestern portion of the quadrangle.

Water management is critical in this high desert environment, illustrated by several reservoirs and isolated springs such as Lisbon Spring and Sop Spring. Topographical landmarks like Big Indian Rock and Summit Point anchor the survey, which also documents the winding paths of Big Indian Wash and East Coyote Wash. The boundary lines between San Juan and Montrose counties further define the political geography of this remote territory during the mid-1950s.
