Malakoff Diggins was California's largest hydraulic mine. While the location had been visited by smaller scale miners before attracting the investor money needed to embark on a large hydraulic mining operation, early forays with pick, sluice, and pan were met with mixed results, earning the area the name "Humbug."
Hydraulic mining techniques found their way to Georgia and revived the state's gold economy, but at a cost. Hoses blasting jets of water against hillsides unveiled more southern mountain gold, but at the expense of the mountains and valleys themselves. ... sufficiently rapid to carry off the tailings." The gold would remain and the debris ...
