Fantastic video. I drove several of these machines while working at the Columbia Icefield in Jasper National Park, Canada - as a tour guide on the Athabasca Glacier - in the summers of 1980 and '81. They were a lot of fun to drive. The machines we drove used wheels to steer at the front (not skies) as we drove partly across a gravel parking lot and down a rocky hill to the glacier. It is great to see these machines so beautifully restored and in their natural, very beautiful environment in deep snow.
