1949 Map of Rancho Santa Fe

About this map

Rancho Santa Fe and its surrounding inland valleys are captured here just as post-war development began to reshape this part of San Diego County. The map details the transition from large land holdings like the Osuna and Fairbanks Ranch to more defined residential clusters such as Olivenhain and Harmony Grove. This era shows a landscape where agriculture and resource extraction still maintained a heavy footprint, evidenced by the Pyrophyllite Mine and a Stone Quarry (Aban'd) near the San Dieguito River. The complex water system, crucial for the region's growth, is prominently displayed through the San Dieguito Reservoir and the western edge of Lake Hodges. Dominating the northern horizon are high points like Double Peak and Mt. Whitney, overlooking the winding courses of Escondido Creek and San Elijo Creek.
