This guy decided to go for a ride with his liquid image video goggles, on his snowmobile in the beautiful snow fields of Wyoming, when he nearly went over a cliff. When he realized he was right on top of this cliff, he stopped, but unfortunately the snow gave way underneath him.
There is a small article about this in the Courier Mail.
