Lost California Treasure

Great Blue Lead at Forest City and Bald Mountain

Forest City and the Bald Mountain drift mine sat on the famed Great Blue Lead, a buried auriferous channel that drove some of Sierra County's most persistent lost-channel speculation. Historical accounts describe the Bald Mountain operation tunneling deep into the mountain, taking coarse gold and very large nuggets from the blue-gravel channel, and sustaining a major boomtown economy. The broader legend is not that the district vanished, but that segments of the old channel repeatedly appeared, pinched out, and were effectively 'lost' and rediscovered by successive miners. That makes the Great Blue Lead one of the strongest northern-California lost-mine landscapes even though the district itself is well documented.

Field Research Notes

Do not assume any old adit is open or safe. The smart hobbyist approach is claim-and-parcel research, reading old channel descriptions, and walking only on clearly public roads or interpreted historic-town areas. Many seemingly abandoned workings in this district sit on private or patented ground, and collapsed drift mines are a serious hazard.
