Ski Cutting in Slack Country

This must have happened a day or two after the last storm. Hard to see this fracture line and even harder to see what looks like ski cutting in these photos but with my binoculars it was fairly clear. The unfortunate thing is this was done directly above a regularly travelled slack country route. Maybe I'm wrong, but it sure seemed the tracks told the story. Anybody else remember the 2 Swedish girls killed by an innocent ski cut from another group above? It was behind Fish Bowl at the lower end of Polaris Bowl.
