Comments
Visibility was poor for much of the trip. We had to wait for moments of clearing before skiing certain lines to ensure a visual on each person. Overall, snow conditions were very enjoyable with a few inches of new powder. We did find evidence of an older, very large slide near the base of the bowl.
