大陆分水岭
The range lies in the northwest Chihuahuan Desert and the extreme northwest end of the range lies in southeast Grant County. It is here that the Continental Divide of the Americas crosses the range, turns northwest, then west, and south at the north perimeter of the north–south Playas Valley. The continental divide continues south into Mexico on the western perimeter of the Playas Valley, through three mountain ranges, the Pyramid, Animas, and San Luis Mountains (New Mexico).
