1959 Map of Harper Canyon

About this map

Anza-Borrego Desert State Park dominates this desert landscape, characterized by the dramatic rise of the Vallecito Mountains and the sprawling floor of Lower Borrego Valley. In the late 1950s, this area remained largely primitive, navigated primarily by a network of Jeep Trails that connect remote landmarks like Harper Flat and the Elephant Tree Area. The map reveals a precarious relationship with water, noting both the Old Kane Spring and the Dave McCain Spring (Dry). Complex drainage patterns are etched into the terrain through various desert washes, including Olla Wash and Oyster Shell Wash. Notable geological formations such as the Mud Palisades and Hapaha Flat illustrate the erosive forces at work within this arid San Diego County environment.
