Hi,
This accident happened near where I used to live so I heard a lot of the details from the residents there.
The snowmobile trail groomer plunged through thin ice and the driver managed to escape through the roof hatch onto shore. It was a very cold night (-22*c) and the driver only had on jeans, a flannel shirt and boot liners (the groomer cab was heated). His cell phone would not function because it got wet. He managed to make it the 1.6 km to the edge of the highway but perished at that isolated location of hypothermia.
