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. It is the largest wooden hull,
bucket line dredge in North America, and an example of corporate industrial mining in Canada.
Dredge No. 4 is one of the 'National Historic Sites of Canada' in the Klondike.
