Notes

Toured much of the Hyalite zone yesterday.  Winds calmed, sun came out mid day.  1” of new snow and 3” the day before.  Skiing was great.  Saw a couple huge cornices that had broken off.  From the top of Devide peak we observed what looked like a cornice release above the headwaters of storm castle creek which triggered a slab, east facing aspect.  Looked to be several feet deep and ran a long way. No other signs of instability observed.  Great skiing. Solar aspects were saturated by the afternoon.
