1964 Map of Sierra Blanca SW

About this map

The Quitman Mountains dominate this high-desert landscape in Hudspeth County, their ridgeline bisecting the terrain between the expansive Quitman Canyon to the west and the drainage of Red Light Draw to the east. This 1964 field-checked survey reveals a rugged ranching environment where life and movement are dictated by scarce water sources and traditional routes. The historic Old Spanish Trail cuts through the northeast, tracing a path through the flats toward the Beargrass landmark. Isolated homesteads and cattle operations such as Cowan Ranch and Tammin Ranch are supported by a sparse network of improvements including Davis Pond, West Windmill, and Sevenmile Tank. The topography here is exceptionally detailed, illustrating the complex drainage patterns and rocky outcrops that defined the Trans-Pecos ranching era before modern infrastructure further altered the backcountry.
