When this massive wooden-hull gold dredge was in operation (1913–59), it ate rivers whole, spitting out gravel and keeping the gold for itself—on one highly productive day it sucked up 800 ounces. These days the dredge occupies a spot along Bonanza Creek about 10 miles southeast of Dawson. Parks Canada used to conduct tours, which may resume in the future, but for now offers a brochure extolling "the largest wooden hulled, bucket line gold dredge in North America." The dredge is still worth a stop, if only to ponder the geology and economics that made it viable to haul this enormous piece of equipment into the middle of nowhere at a time when gold only brought $20 an ounce. You can pan for gold yourself in Bonanza Creek, where the Klondike Visitors Association offers a free claim for visitors. Bring your own supplies (almost every gift shop in town sells pans).
