About this map

Big Bend National Park defines the lower half of this landscape, where the Big Grapevine Hills and Avery Canyon rise from the desert floor. The geography is shaped by the drainage of Tornillo Creek and Cottonwood Draw, highlighting a region where water sources like Grapevine Spring and Neville Spring were critical for survival and early ranching efforts.

Evidence of human activity and natural history is scattered across the terrain, from the Rosillos Mountain Ranch in the north to a lone Grave near the southern boundary. The inclusion of a Fossil Bone Exhibit near the eastern flats underscores the geological significance of the area. This 1971 survey captures the transition of the land into a protected wilderness, maintaining a record of the remote tracks like Dagger Flat Road and the isolated peaks of the Rosillos Mountains.
