About this map

Downieville and Quincy serve as the primary hubs in this late-19th-century survey of the northern Sierra Nevada, a region then defined by its intense mining activity. The landscape is a complex network of deep river canyons and high ridges, where the North Fork Yuba River and the Middle Fork Yuba River dominate the southern half of the sheet. Industrial history is etched into the terrain through numerous named workings, such as the Empire Mine, Young America Mine, and the Pliocene Mine near Cornish House.

Gold Rush era settlements, some already reduced to remote outposts by this date, are scattered across the ridges and flats. Researchers can trace the proximity of places like Howland Flat, Poker Flat, and Whiskey Diggings, which were connected by early transit routes like the Sierra Turnpike. The map also captures several family ranches and waypoints, including the St. Charles Ranch, Otis Ranch, and the Sulphur Spring House, providing a detailed view of the localized economy before modern infrastructure arrived.
