1942 Map of Adelaida

USGS Topo · Published 1942

About this map

The Santa Lucia Range dominates this 1942 landscape, serving as a backdrop for the isolated homesteads and mining operations of western San Luis Obispo County. At the center of the sheet, the small settlement of Adelaida serves as a hub for the surrounding livestock operations like the Kentucky Ranch and Santa Rita Ranch. The region's industrial footprint is defined by the Klau Mine and the Oceanic Mine, while the northern reaches show the expansion of the Camp Roberts Military Reservation during the war era. Small, one-room schoolhouses like Mammoth Rock School and Lincoln School are scattered throughout the canyons, reflecting a rural social structure anchored by family-named landmarks and a network of unpaved tracks such as the Paso Robles Road.
