1943 Map of Tent Hills

About this map

The Diablo Range dominates this 1943 survey, where the borders of Monterey, Kings, San Luis Obispo, and Kern Counties converge in a landscape of sharp ridges and winding canyons. This wartime edition, compiled by Fairchild Aerial Surveys for the Army Corps of Engineers, focuses on the high-elevation terrain of the Tent Hills and the transition into the McClure Valley. The map reveals a remote pastoral economy through family-named landmarks and homesteads, including Fahey Ranch and the Iron Spring Ranch. Significant transit corridors like Polonio Pass provide passage through the peaks, while seasonal drainages such as Cottonwood Creek and Avenal Creek define the watershed. The inclusion of triangulation stations like USC & GS Avenal and USC & GS Polonio reflects the meticulous geodetic control required for this early aerial photogrammetric study.
