2019 Map of Alamo Spring

About this map

Alamito Cr serves as a central drainage through this Presidio County landscape, where an intricate network of intermittent waterways carves through the high desert terrain. The convergence of Cienega Cr with larger systems illustrates the complex hydrology of the Big Bend region, where seasonal water flow dictates the geography. Surface transportation is defined by the winding path of Hwy 169 and the intersection with Casa Piedra Rd, routes that follow the natural contours of the land to connect remote ranchlands and homesteads. Further east, Alamo Cr and Black Hills Creek mark the transition toward more varied elevations, while Arroyo Monias and Tortolo Cr trace the western boundary of this drainage basin. This 2019 survey by the U.S. Geological Survey documents the enduring rural character of West Texas, where land use remains tied to these vital watercourses.
