About this map

Columbia State Park serves as a preserved centerpiece in this late-1940s landscape, reflecting the region's deep gold-mining heritage. The map records a dense network of claims and works, from the Golden River Mine in the north to the Springfield Mine and Experimental Mine further south. The geological prominence of Table Mountain and the canyon of the Stanislaus River dominate the terrain, creating a backdrop for historic settlements like Vallecito and Douglas Flat.

Industry and transport of the era are visible through features like the Columbia Airport, the Parrotts Ferry Bridge, and numerous quarries including the Marble Quarries near the river. Smaller, named locales such as Squabbletown, Shaws Flat, and La Honda Park highlight the localized nature of community development following the initial gold rush. The map also delineates the Stanislaus National Forest boundary and several reservoirs including Matelot Reservoir and San Diego Reservoir.
