1959 Map of Borrego Sink

About this map

Borrego Valley is defined by its arid landscape and early mid-century development within the expansive Anza-Borrego Desert State Park. In the late 1950s, the area shows a shift toward tourism and private aviation, evidenced by the Borrego Air Ranch and Desert Lodge. Agricultural and ranching interests are anchored by the Ensign Ranch and its associated Ensign Ranch Air Strip. The terrain is characterized by the low-lying Borrego Sink and the dramatic elevations of the Yaqui Ridge and Vallecito Mountains to the south. Historically significant routes like the Old Borrego Valley Road and the Old Kane Spring Road trace the movement of early travelers through this desert corridor. Water, always critical, is marked by ephemeral features such as Coyote Creek and the San Felipe Creek wash system, which drain toward the sink.
