1960 Map of Clark Lake NE

About this map

The Santa Rosa Mountains dominate the northern half of this 1960 survey, their steep slopes giving way to the broad expanse of Clark Valley to the south. This arid landscape is largely defined by the sprawling boundary of Anza Borrego Desert State Park, which encompasses much of the southern terrain and the lower reaches of drainage systems like Rockhouse Canyon and Butler Canyon. Human presence is sparse, marked primarily by primitive transit routes such as the Cactus Spring Foot Trail and the Rockhouse Trail, alongside a few isolated structures including a Shack and unidentified Ruins tucked near the canyon walls. The map reveals a transition between Riverside and San Diego counties, highlighting a period when the desert remained largely inaccessible, save for a few Jeep Trails and a rare spring providing water in the high desert environment.
