About this map

Big Bend National Park dominates the western half of this 1970s landscape, where the high desert terrain of Brewster County meets the dramatic peaks of the Sierra Del Carmen. The map documents the protected lands of the Black Gap Wildlife Management Area and the vast Dagger Flat basin, a region defined by arid watercourses and isolated livestock improvements.

Evidence of historical activity is sparse but telling, found in the lonely Dagger Tank and a single Prospect located near the Wildlife Management Area Boundary. Topography is the primary story here, from the prominent Dagger Mountain to the sharp ridges of the Sierra Del Caballo Muerto, with a network of Jeep Trails and drainage systems like Nine Point Draw providing the only navigable routes through this segment of the Chihuahuan Desert.
