I see this local snowmobiler had a video go viral, and it is getting lots of national attention. This is the exact same area I flew over (I can tell you the direction he was going by the way the snow is drifted, when I went over this 10K or so ridge line snow was curling off of it, that got my full attention as I was headed into a valley right on the other side, the Box Y Lodge) right east of Afton Wyoming.
Another local made the paper a few weeks ago when he was in the same area, and got tangled up in his flipped machine. He lost one arm up to the elbow, those things are dangerous
