Ty ran Cataract Canyon on one my trips @ 70,800 CFS in an aluminium canoe back in 1997. He ran all three big drops, but had to swim the last one. That dude has always been crazy.
I'm pretty sure the same guy ran this in 1997 in an aluminium canoe while filming a commercial for Gatorade or something...
If you go to youtube and look through the other videos posted by monette39 you can supposedly find the clip of him going through,but I can't find it. These are largest rapids in North America.
