About this map

Rio Grande serves as the dominant geographic and political spine of this borderland survey, dividing Maverick and Webb counties in Texas from the Coahuila region of Mexico. To the west, the landscape is defined by the significant population centers of Zaragoza, Nava, and Allende, connected by the arterial routes of Mexico 57 and Mexico 2. This Mexican portion of the map reveals a dense network of agricultural and urban development that stands in sharp contrast to the more open, creek-scored ranchlands on the American side.

Tracing east from the river, the terrain rises into the dry brush country of Texas, marked by numerous drainage systems including San Ambrosia Creek and San Juan Creek. This area is characterized by a high concentration of livestock infrastructure, featuring numerous named water sources such as Coyote Tank, Barro Azul Tank, and Salt Well. Landmarks like Cathedral Rock and several landing strips provide orientation points across this expansive, sparsely populated border territory.
