This avalanche occurred while skinning up along a ridge-line. Near the top the slope opened up more while exiting the ridge and it got somewhat deeper, and about 10-20ft below the top of the slope, the top was triggered by skinning. Both members of the party were carried 20-30 feet down the slope and were able to self rescue with only a very minor knee strain. Minor wind slab was observed in other regions of the tour, but it did not seem reactive upon skiing. Shortly before triggering, a roughly 6 foot shooting crack was observed when skin turning uphill. The trigger propagated out into the snow bowl to our east.
The failure was in the layer between snow that fell prior to 11/14, and the snow that fell overnight on the night of 11/14-11/15. There was heavy wind transport in the morning when touring.
