A large natural slide was observed near the Maid of the Mist up Hyalite Canyon. This slide occurred on a heavily wind loaded slope and was likely triggered by a natural cornice drop. It's hard to say what layer this slide failed on, but there is a good chance it was the near surface facet layer formed in the middle of February. Photo Andrew Newman
