Feather River — Yuba County

Gold Mining Site CA • Yuba County County
Description
I have a friend that is doing real well on the Feather River with a 5" dredge. He is on some club claims. At Marysville and Yuba City, regional gravels of the Feather River especially upstream toward the mountains are very rich in placer gold.
