Manzanita Mine, California

Manzanita mine, near Sweetland, Nevada County, California, in 1905. Extensive hydraulic mining of the gold, silver and platinum deposits found here began in the early 1850s. Beyond the buildings is a ridge bearing trees on its crest. The camera stood on a similar ridge. The outer slopes of the ridges and the tabular top of the intervening hill are parts of the original surface before the mining. The estimated volume of the entire excavation at this point, including the Manzanita and American mines, was 47, 900, 000 cubic yards
