Not long after gold was discovered in the central Yukon, dredges were introduced to the region. One of two dozen dredges that worked this area, Dredge No. 4 rests on Claim 17 Below Discovery on Bonanza Creek near the spot where it ceased operations in 1959. Dredge No. 4 is the largest wooden hull, bucket line dredge in North America and is a significant example of corporate industrial mining in Canada.
Dredge No. 4 National Historic Site is one of the National Historic Sites of Canada in the Klondike
