    Good friend of mine has owned a couple of hundred acres up Cracker Creek in Sumpter forever that has several gold mines on it and great elk/deer hunting! He was telling me the story behind that dredge. It seems that when it was decommissioned and put to bed one of the old boys in town bought it for a song. Everyone in town thought he was crazy, unbeknownst to them it seems those old dredges left a lot of gold in the bilges and various other hiding spots. The old boy cleaned out the dredge with a fine tooth comb. Made enough to pay for it and a bunch more. He then donated it to the city for a historical monument. Don't know how much truth is in that story, but have heard it from more that one local in the local pub:drinkup.

    There were several of those placer mining dredges in the Yukon. They dug they're own pond to float in and all the tailings that came out of the sluice boxes went up a long conveyor belt (stacker) and essentially backfilled the pond behind it. The ground ahead of the dredge had to be thawed as they have permafrost that far north. They thawed the ground by pounding in water jets that sprayed cold water into the ground causing the ground to thaw and allowing it to be mined. Those dredges were usually built by Bucyrus Erie. My dad use to work up there in the early to mid seventies at a couple of lead/zinc mines and at an asbestos mine in northern B.C. And in 1998 my dad was up by Dawson City for the Centennial 1898-1998 and there is a restored dredge unit #4 that was rescued by the Canadian Government in '80's or '90's and put on permanent display.

    We toured one of these outside of Fairbanks Alaska some 20 years ago. I can't remember all the specs of it, the guy said it could be heard a mile or so away when it was running. There was primary [high voltage] wire to it from the shore, 3 phase. The gears in it were massive. A sluice type setup inside, I think they poured mercury in at some point, the gold stuck to it.

    They didn't pour mercury in it that's used in a different process to refine the gold after it's been sluiced and panned.

    I wonder if they lowered the water level and really got down to bedrock, or did they just dig down to the ~`12 or ~20 feet that the boom would reach?

    There is a fascinating post on Livejournal with pictures of a floating dredge in use quite recently in Russia. Unfortunately the entry is in Russian, but the language translator in Google Chrome does a half decent job on it: http://mishakiselev.livejournal.com/5328.html

    Speaking of which...

    I was watching Bering Sea Gold tonite and kept seeing a dredge in the background, looking like it was land-locked. So I found it...
