1948 Map of Columbia

About this map

Columbia Historic State Park preserves the townscape of the gold rush era, shown here during its late 1940s status alongside the neighboring settlement of Springfield. This region of the Mother Lode is densely packed with mid-century mining operations and geological landmarks, including the Sheep Ranch Mine, Marble Quarries, and the depths of Moaning Caves. The landscape is defined by the steep descent of the South Fork Stanislaus River, which powered industrial sites like the Stanislaus Powerhouse. To the north, Calaveras Big Trees State Park and the Stanislaus National Forest dominate the high ground above Hathaway Pines. This survey captures the transition from a traditional hard-rock mining economy to one of conservation and early tourism, with the Sierra RR and Columbia Airport providing critical transportation links to the surrounding Calaveras Co and Tuolumne Co communities.
