The Quincy Dredge Number Two (previously known as the Calumet and Hecla Dredge Number One) is a dredge currently sunk in shallow water in Torch Lake, across M-26 from the Quincy Mining Company Stamp Mills Historic District and just east of Mason in Osceola Township. It was constructed to reclaim stamping sand from the lake for further processing, and was designated a Michigan State Historic Site in 1978.
