About this map

The Rio Grande serves as the dominant geographical and political boundary in this borderland region, marking the divide between the Usa and the Estados Unidos Mexicanos. This arid landscape is defined by its drainage systems and steep relief, where water is the primary sculptor of the terrain. Narrow corridors like McComb Canyon, Chillicote Canyon, and Cold Water Canyon funnel seasonal runoff toward the river, illustrating the complex hydrology of the High Desert.

A crucial reliable water source in this environment is McComb Spring, located near the upper reaches of McComb Creek. While the terrain appears sparsely settled on this modern survey, the naming of features such as Walker Creek and Musgrave Canyon suggests a history of local land use, likely tied to ranching or early surveying efforts in Presidio County. The topographical detail reveals the deeply incised paths carved by these ephemeral streams as they descend toward the international boundary.
