Beautiful California in 1914

A Placer Hydraulic Mine 

(Remember these prints show scenes as they looked more than century ago.)

Early placer miners in California discovered that the more gravel they could process, the more gold they were likely to find. ... Hydraulic mining became the largest-scale, and most devastating, form of placer mining.
