About this map

Coastal dunes and agricultural valleys define this mid-century portrait of San Luis Obispo County. The Southern Pacific RR tracks parallel the Pacific shoreline, serving a string of communities from the seaside resort atmosphere of Pismo Beach and Shell Beach to the inland hub of Arroyo Grande. In the southern portion of the map, an intricate network of freshwater bodies including Black Lake, Jack Lake, and Oso Flaco Lake sits tucked behind the massive Sand Dunes of the Oceano coast.

Industry and local services are well-documented, with numerous Oil Wells and Oil Tanks marking the transition from the Santa Lucia Range to the coast. Educational and social anchors such as Oak Park Sch, East Santa Fe School, and Hidden Valley Hot Springs illustrate the established rural community structure. Near the north, Laguna Lake and San Luis Obispo Creek drain toward San Luis Obispo Bay, while the Pismo Airport signals the era's growing infrastructure.
