About this map

Sierra Nacimiento dominates the central landscape of this 1939 survey, separating the arid western basins from the Jemez Indian Reservation and Zia Indian Reservation. At the confluence of the Rio Salado and Jemez River, the village of San Ysidro serves as a focal point for movement through the valley, located near the southern terminus of the Santa Fe Northwestern (Abandoned) rail line. The presence of CCC Camp No 8 N near Ojo del Espiritu Santo reflects the Depression-era public works projects that shaped the management of these New Mexico lands during the late 1930s.

The western half of the map is defined by the Ojo Del Espiritu Santo land grant, where scattered ranching outposts like Rincon Ranch and Marquez Ranch are situated among a complex network of arroyos and springs. Key water sources such as Cachana Spring and Soda Spring underscore the importance of reliable water in this high-desert environment, while the Jemez Trail provides a route through the rugged canyons of the Cañon de San Diego.
