About this map

Gold-country history and early transportation routes define this landscape in the Sierra Nevada foothills, where the Southern Pacific railroad cuts through the canyons of the Bear River and Secret Ravine. The map preserves the footprint of several historic settlements, including the uniquely named You Bet and Red Dog, which sit adjacent to extensive Diggings and Placer Diggings that reveal the scale of hydraulic mining in the region. Near the Nevada and Placer County line, the steep grades of the railroad grade are marked by notable landmarks such as Cape Horn and the site of Secret Town.
