1919 Map of Adelaida

About this map

Adelaida serves as the central hub of this 1918 survey, which documents the interior highlands of the Santa Lucia Range just before the modern development of coastal California. The landscape is defined by a network of rural schoolhouses and small settlements connected by winding mountain roads like the Templeton Road. Educational landmarks including Lincoln School, Summit School, and Josephine School indicate a dispersed but established agricultural community. In the southern reaches, the Black Mine sits near the headwaters of Black Mountain (noted by label), while the German Church stands as a cultural marker in the eastern canyon country. The intricate drainage patterns of the Nacimiento River and Jack Creek illustrate a topography where narrow valleys and steep ridges dictated the placement of family holdings like Williams Ranch. This document, produced through a cooperation between the War Department and the state, provides a detailed inventory of San Luis Obispo County's rural infrastructure at the end of the First World War.
