About this map

Anza-Borrego Desert State Park dominates this mid-century landscape, revealing a complex network of seasonal drainages and remote desert outposts. The survey highlights the essential, often ephemeral water sources critical for travel through the Vallecito region, including Old Kane Spring and the Dave McCain Spring (Dry). The terrain is defined by dramatic geological features such as the Mud Palisades and wide desert basins like Harper Flat and Hapaha Flat.

Transport through this arid corridor relied heavily on primitive routes like the Old Kane Spring Road and various Jeep Trails that snake through the Mountains. This map also delineates the Elephant Tree Area, a specific botanical zone within the park, and follows the paths of multiple washes including Fish Creek, Stone Wash, and Oyster Shell Wash, which illustrate the active erosion patterns of the California desert.
