About this map

The Santa Lucia Range dominates this mid-century survey of the California coast ranges, revealing a landscape defined by isolated ranches and early quicksilver mining. The small community of Adelaida serves as a central point, surrounded by local landmarks like the Adelaida Cem and several rural schoolhouses including Lincoln Sch and Summit Sch. The industrial history of the region is evident through the presence of the Klau Mine and Oceanic Mine, representing the mercury mining district that once flourished in these hills.

Transportation and land use are shaped by the winding paths of Las Tablas Creek and Jack Creek, which cut through the high ridges of Cypress Mountain and Lime Mountain. In the northeast corner, the Camp Roberts Military Reservation occupies a portion of the terrain along the Nacimiento River, illustrating the military footprint established during the preceding war years. This map preserves a record of the backcountry before modern development, noting family holdings like Chimney Rock Ranch and the Kentucky Ranch.
