1971 Map of Agua Adentro Mountain

About this map

The Bofecillos Mountains dominate this 1971 study of the high desert of Presidio County, showing a landscape defined by volcanic peaks and essential water sources. Along the northern edge, Rancho Viejo Spring and Agua Adentro Spring represent critical oases for cattle and ranching operations in a territory where water dictated survival. The topography is deeply carved by drainage systems like Bofecillos Canyon and Las Burras Canyon, while prominent landmarks such as Elephant Mountain and Bofecillos Peak provide navigational anchors. Early industrial activity is evidenced by a Gravel Pit and 3 Prospects near the peaks, while the southern boundary reaches toward the Rio Grande frontier between the United States and Mexico, highlighting the area's role as a rugged borderland crossroads.
