World’s Largest Gold Dredger
at Work in Yuba County ,
Largest gold dredgers in the world work along the Yuba River in Yuba County, digging 110 feet below the surface of the water. This picture of a typical dredge, shows the folds of gravel in symmetrical design, as they are
left by the gold-extracting machine. The flat ground is that yet to be worked.—Photo by courtesy Sac’to Union.
