Just heard that two or three days ago a 27 yr old Alberta man was killed when his pick up went through the ice 100km north of Yellowknife. This was not on the Tibbett to Contwyoto road, as far as I know. He was working for an exploration company, three of them were in the truck collecting wood with which to build some sort of a shelter from which they could ice fish. The truck went through and two guys managed to jump out, suffering only frostbite. The third man went down with the truck and is presumed drowned.
