About this map

Jacksonville and the canyon of the Tuolumne River define this 1949 topographic study of Tuolumne County. This era captures the critical infrastructure of the Hetch Hetchy system, including the Hetch Hetchy Aqueduct and the Inclined Railroad near the Moccasin settlement. The map serves as a vital record for mining history, pinpointing operations like the Harriman Mine, Clio Mine, and McAlpine Mine before further 20th-century landscape changes.
