More detailed information about the avalanche: 

A solo skier entered the steep chutes south of Negative 1 and triggered a size D1 wind slab that ran the width of the chute, breaking above him. He was able to move to the side and allow the debris to pass, and the debris triggered a second shallow wind slab that was 75 ft. wide and the combined debris from both slides ran ~500' and was size D1.5.
