1978 Map of El Morro Ranch NW

About this map

San Pablo Draw meanders through this high-plains landscape in Guadalupe County, defining the drainage patterns of an area dominated by ranching interests in the late 1970s. The presence of the Perez Ranch in the southwest corner and a network of named water sources like Cañada de Brehedo highlights the critical importance of water management in this arid environment. The map specifically identifies several key infrastructure points for livestock, including the Upper Brehedo Windmill, Mc Gee Windmill, and Old Boney Windmill. These features indicate a terrain where scattered windmills were the primary landmarks for navigators and ranchers alike. This detailed topographic study captures a specific moment in New Mexico's pastoral history where family-named rangelands and isolated water pumps served as the primary nodes of human activity across the open country.
