Observation

Description of Snow, Weather, and Avalanche Conditions:

Mostly skied lower angle terrain but saw several instances of avalanches getting triggered when we briefly went into short steeper zones. One skier was briefly caught and carried but not buried, no injuries. Would say at that time around 6 inches of new storm snow had accumulated and slid, probably at the old snow interface which was still powdery in this area. Significant propagation.
