About this map

The Quitman Mountains dominate this high-desert landscape of Hudspeth County, where complex topographic contours reveal a network of canyons and drainage systems characteristic of the Trans-Pecos region. In an area where water is the primary driver of the historical ranching economy, the map documents critical catchment points such as Sevenmile Tank, Fivemile Tank, and Davis Pond. These localized water sources supported livestock and travelers long before the advent of modern infrastructure.

Transportation through this isolated terrain is defined by rugged corridors like Quitman Pass Rd, which winds through the mountain gaps, and Cowan Rd to the north. To the east, the broad expanse of Red Light Draw suggests a massive natural wash, while Big Tank Canyon cuts into the southwestern slopes. This 2019 survey provides a contemporary perspective on a desert landscape that remains largely defined by its natural barriers and sparse water features.
