1948 Map of Columbia

About this map

Mining operations and historic Mother Lode settlements define this 1948 survey of the Sierra Nevada foothills. The Stanislaus River carves a deep path through the center, separating Calaveras and Tuolumne counties, while the massive Table Mountain formation dominates the southern terrain. The area around Columbia is particularly dense with historical markers, including the Columbia Historic State Park and numerous hard-rock sites such as the Experimental Mine and Springfield Mine.
