Snowmobiler triggered unintentionally. Climbing the lee-ward face of a short steep hill. The track that triggered it is in the upper right corner of the pictures. A second snowmobiler (me) was beginning to climb as the avalanche was triggered. I was able to pin the throttle and escape unharmed and untouched (the U-shaped track at the toe of the slide is the turn out).
