2021 Map of Columbia

About this map

Columbia and the surrounding Gold Country terrain of Calaveras Co and Tuolumne Co are meticulously documented in this 21st-century survey. The landscape is defined by its deep mining history and complex water systems, including the O'Neil Ditch, San Diego Ditch, and the S Ditch that weave through the limestone hills. Settlement patterns are concentrated around historical centers like Vallecito, Springfield, and Shaws Flat, each flanked by numerous burial grounds such as Columbia Odd Fellows Cem and Saint Anne's Catholic Cem. Significant elevation changes are marked by Table Mtn and Bell Hill, while the Stanislaus River and the New Melones Lake reservoir illustrate the region's hydraulic geography. This map also tracks modern institutional footprints like Columbia College and the Columbia Airport amidst the dense network of gulches and canyons.
