About this map

Cibolo Creek and its many seasonal tributaries dominate this high-desert landscape in Presidio County. The drainage network is characterized by deep erosional features like Arroyo Chillon and Arroyo Mimbroso, which cut through the arid terrain. Human presence is sparse, marked primarily by the isolated Arroyos Ranch and a series of survey benchmarks including Presidio North Base BM 3518 and Presidio South Base BM 3093, which served as critical control points for mapping the Texas borderlands.

Water sources are vital in this environment, with La Boquilla Springs and scattered wells providing the only reliability in a land defined by dry washes. The Escondido Trail and various Jeep Trails offer the primary means of navigation through the complex topography, connecting remote points like Twin Mills. This survey captures the region just before the late-1970s, showcasing a landscape where ranching and surveying were the primary drivers of geographical naming.
