DANGEROUS UNSTABLE CONDITIONS EXIST ON STEEP SLOPES. Human triggered avalanches are likely, especially during the warmest portions of the day. Yesterday there were multiple large slides remotely triggered by skiers on a variety of aspects. A snowmobiler was partially buried and seriously injured on the approach to Jules Bowl near Brooks Lake. Humans who venture onto steep mid and upper elevation slopes could trigger hard or soft surface slabs up to three feet deep. The potential also remains for humans to trigger deep hard slabs to the full depth of the snowpack. Natural avalanche activity is possible.
