Notes

The Big Sky and YC Ski Patrols triggered numerous avalanches during control work. Most slides were fresh wind slabs created by the 4-6" of new snow and strong winds. Most stayed confined to the upper layers of the snowpack, but one slide at the YC broke on facets near the ground. This slide broke 2-3' deep and ran nearly full path.
