1987 Map of Engine Mountain

About this map

Engine Mountain and the surrounding desert landscape of the Peloncillo Mountains area are detailed in this late-twentieth-century study of the Arizona-New Mexico borderlands. The terrain is defined by a series of steep drainages, including Antelope Canyon and Grayhorse Canyon, which carve through the high ground of Horsefoot Mountain. The map provides specific locations for vital desert water sources such as Rockhouse Spring and Indian Spring, which historically supported ranching and movement through this arid environment.
