While traveling up Beartrap Fork, we noted this D1.5 avalanche on the skiers left side of the approach gully. We are unsure when this avalanche exactly occurred during the storm. The debris went into the typical skin track with up to 4-5' of snow in certain places, and while small, this slide could have buried a human considering it went into a gully. We assume (based on pit results noted below) that this released sometime during the 12/1-12/2 storm, on the the persistent NSF layer. Collapsing and cracking was noted on low/mid elevations on all aspects.
