Analysis

During an approach to a 9100 foot high snow covered landing site the wind shifted to a tailwind condition. The pilot elected to continue and attempted a skid on landing. While skidding through the snow the left skid impacted rising terrain underneath a 12 inch snow pack. The left skid separated upwards and the helicopter rolled over.
