Hydraulic Gold Mining, 1875

Hydraulic mining was a variation on ground sluicing where the water delivered to the site would be shot through a nozzle at high pressure onto the face of the cliff, thereby washing away tons of boulders, gravel, dirt, and, in the hopes of the miners, ounces of gold. These "water cannons" were indeed very powerful—they could throw 185,000 ...

Mining History and Geology of the California Gold Rush

Gold mining evolved from hydraulic mining of unconsolidated placer deposits in the early days of the Gold Rush, to underground mining of hardrock depos-its, and finally to large-scale dredging of low-grade gravel deposits, which in many areas included the tailings from upstream hydraulic mines. By the mid-1850s, in areas with suf-ficient ...
