Golden Age of Gold Dredges
June 2002 by Frank Lorey IIIOver one hundred years ago, gold mining in California saw a radically new method tried out in the major rivers of the Central Valley.

Shirttail was worked heavily in the old mining years, but they didn’t clean it out. Present day prospectors and dredgers have done well, especially as Shirttail gets closer to the North Fork of the American.
