Avalanche: Superior

Coming from a chute that had seen quite a bit of skier compaction (towards the top tracks were still visible) underneath a terrain feature where multiple starting zones ended in one runout zone. New snow on a hard bed surface. We ignored warning signs: snow sluffing of rocks, and an increasing PI rate. Two people were caught (out of a party of four). Due to visibility we could not see the starting zone but the debris pile in the apron was 80x300 ft. Debris was more than 7 feet deep in places.
