About this map

The Santa Lucia Range dominates the terrain of this 1948 survey, where the drainages of Paso Robles Creek and Santa Rita Creek carve through the landscape. Located in a transition between the coastal mountains and the interior, the area is characterized by rural ranching life and a network of country schools that anchored these remote communities. Notable landmarks include the Kentucky Ranch in the north and the Santa Rita Ranch to the south, connected by winding routes like Dover Canyon Road.

Educational sites are frequent, with the Summit Sch, Oakdale Sch, and Asuncion Sch serving families scattered throughout the valleys. The map documents the intricate hydrography of the region, including Jack Creek and Willow Creek, which flow toward the broader Paso de Robles area. The topographic detail captures a landscape of cattle ranching and viticulture foundations before the significant expansion of modern irrigation and infrastructure.
