General Comments 2

Not many people made it out onto steeper upper elevation hills today, but a couple people started riding smaller hills only to trigger these avalanches right outside of the Warming Hut.....Once again- I can say I'm glad nobody got caught in these scary avalanches....

You could probably trigger much larger avalanches in the bigger terrain surrounding this slope this weekend...
