Signs of Unstable Snow

None reported

Observations

Lots of wet loose that were observed to be triggered from snow/ice falling from the cliffs above as the sun started to hit certain aspects. The loose snow would generally slide down the nearest couloir and bigger ones would trigger avalanches. The most major ones went down Bryant Couloir and skier's right by the source lake face of Chair Peak at 4600' under the 4800' cliff bands. This one almost caught 2 skiers who managed to ski away from the avalanche. There were also small loose snow that came off the south face of the Tooth. All of this happened continuously 10am-1pm which was when my party left since we no longer felt comfortable with the uncertainty.
