The scarred valleys around Dawson speak to the vast amounts of toil that went into the gold hunt. Most emblematic is Bonanza Creek, where gold was first found and which still yields some today. Dredge No 4, 13km off the Klondike Hwy, is a massive dredging machine that tore up the Klondike Valley and left the tailings, which remain as a blight on the landscape. Tours of this Parks Canada site are run by Goldbottom Tours.
Learn about this huge machine, which worked something like a freakish giant worm in a science-fiction novel.
