About this map

Paso Robles serves as the central hub of this 1917–1918 survey, which documents the upper Salinas Valley just as the region’s agricultural identity was firmly established. The Salinas River carves through the landscape, flanked by the Southern Pacific (Coast Division) railroad and a network of named land grants including Santa Ysabel, Huerhuero, and Asuncion. These large tracts suggest the transition from sprawling ranchos to more intensive cultivation, supported by a dense distribution of rural schoolhouses such as Estrella School and Phillips School.

To the north, the San Miguel Mission marks the historic Spanish influence on the area’s settlement pattern. Moving south toward Atascadero and Templeton, the map reveals a countryside connected by early thoroughfares like Parkfield Road and Bakersfield Road. Small community centers like Union, Linne, and Creston provide essential waypoints for genealogists tracing family roots in early twentieth-century San Luis Obispo County.
