About this map

Gold-bearing hills and steep river canyons dominate this late nineteenth-century survey of the Mother Lode region. Settlements like Chinese Camp, Jamestown, and Coulterville anchor a landscape defined by hydraulic mining history and early mountain transit. The Tuolumne River carves through the center of the sheet, joined by the North Fork Tuolumne River and the Clavey River. This era shows the transition from isolated mining camps to more permanent towns, connected by vital crossings like Moffat Bridge and the Split Rock Ferry.

Tracing the foothills into the higher reaches of the Stanislaus National Forest, the map records numerous small workings and prospects such as the Red Cloud Mine and Olsen Mine. Unique landmarks like Bower Cave and the curious naming of Second Garrotte reflect the local lore and social history of the Sierra Nevada foothills before the modern highway system redefined the routes to the high country.
