From IG message on June 11, 2020: "...Just wanted to let you know, I was up by fairy lake this morning, and the new snow we got earlier this week was very much still a hazard. Skinning up the fairy lake basin was deceptive, because most of the new snow had melted out there and it was just refrozen corn, but most of the S and E aspects of that area slid naturally on the new snow. I also triggered a small point release on a NE solar aspect that ended up entraining a large amount of snow as it went and was again surprising because both my partner and I had felt quite safe on the snow we’d been on throughout our approach. It certainly caught us off guard and we got out of there safely, but was just a good reminder to not get complacent."

Skier triggered wet loose at Fairy Lake

A skier triggered this slide on June 11th near Fairy Lake. They were not caught, but it was a good reminder to stay heads up on the snow all year. From message: "...Red is where I triggered it, blue and yellow are the two separate debris piles from it. Nobody was caught, I was the only one involved. It wasn’t a huge slide by any means, but certainly could have run me through some cliffs and buried me."
