I guess this might be what we ran into snow skiing at Vail many years ago. We rode the lift to the top of the mountain. It was a blizzard up there, you couldn't see anything. Then lightening came. I had never run into that before in a snowstorm. They closed the lifts right after we hit the top and the ski patrol corralled everybody together into a controlled group kept us skiing down the hill as fast as the group could make it.
