About this map

The West Nueces River carves a winding path through this portion of the Texas hill country, defining a landscape marked by significant river crossings and topographic landmarks. The river's course is punctuated by several named pools and reliable watering spots, including Mustang Waterhole, Double Waterhole, and Yellow Waterhole, which historically served as critical waypoints for travel and ranching in this arid environment. The terrain rises sharply away from the water at Barrilla Bluff, while the seasonal drainage of Rough Hollow cuts through the western uplands.

Industrial and administrative history is visible in the lower portion of the map, where the Southern Pacific railroad line runs east-west across the scrubland. An Indefinite Boundary separates Kinney and Uvalde counties, reflecting the complexities of surveying this uneven ground. A simple Jeep Trail provides the primary overland access through the northern breaks, illustrating the area's limited transportation infrastructure during the mid-1970s.
