Big Bend National Park serves as the focal point for this 1970s survey, marking the northern gateway to this Chihuahuan Desert landscape. The boundary of the park is clearly delineated as it cuts across the southern portion of the sheet, encompassing the Persimmon Gap Ranger Station and the topographic bottleneck of Persimmon Gap. This passage through the Santiago Mountains has historically been a vital corridor for travel through the region's arid terrain.
