A ski cut on the upper slope easily produced a loose wet slide that ran for several hundred feet. By 11 AM, east facing slopes already were too warm. That combined with the frozen graupel layer beneath the new snow made for very reactive snow. Avalanche size is approximate, but the slide was definitely large enough to send someone for a ride.
