1972 Map of Sibley Hole

About this map

The high desert landscape of Luna County is defined by isolated ranching infrastructure and natural depressions that collect seasonal moisture. In the early 1970s, this area centered on Sibley Hole, a natural catchment that gives the quadrangle its name, and the prominent topographical feature known as the Rim. The land use is clearly agricultural and livestock-focused, evidenced by the presence of the White House Ranch and vital water sources like Brushy Tank and Blanco Tank. Named landmarks such as the High Lonesome Windmill and Board Ranch Windmill underscore the necessity of wind-driven water extraction in this arid terrain, marking specific points of human activity within an otherwise open range.
