On the morning of February 6, 2021, two different groups of people (eight people total) went to ski in the Wilson Glades area of Alexander Basin on the north side of Wilson Peak in Millcreek Canyon. Both groups were ascending when the avalanche happened. Group A was near the top, and Group B was below. This avalanche was likely human-triggered, but it cannot be determined by whom. Six people were caught and fully buried. Only two of them survived.
