1959 Map of Harper Canyon

About this map

Anza-Borrego Desert State Park dominates this late-1950s survey of the California desert, capturing a landscape defined by dramatic geological formations and seasonal watercourses. The map details the complex topography of the Vallecito Mountains and broad open spaces like Harper Flat and Hapaha Flat. A network of historic paths, including the Old Kane Spring Road and various unnamed Jeep Trails, indicates the era's reliance on rugged transportation routes through the arid terrain.
