About this map

The Borego Valley corridor and its surrounding desert peaks are captured here just as World War II-era mapping efforts refined the understanding of this arid landscape. This 1942 road survey highlights the intersection of modern travel and pioneer history at Scissors Crossing, where the Old Overland Stage Route cuts through Earthquake Valley toward the Las Arena Ranch. The transition from the high Oriflamme Mountains to the low Borrego Sink illustrates the importance of water in this environment, anchored by the Yaqui Well and the remote Borrego Spring.

Cultural landmarks of the early desert tourism era appear in the form of Desert Lodge, situated near the mouth of Hellhole Canyon. To the south, the map reveals a complex of dry valleys and washes, including Blair Valley and Little Blair Valley, nestled against the Vallecito Mountains. These features reflect a landscape that, while sparsely populated, was critically defined by its established routes and precious water sources like San Felipe Creek.
