Avalanche Details

Noted recent debris, crowns, etc on both sides of this ridge. Outside these slides did not note much activity in the region on flight both south of Taku Inlet and mainland behind town and Douglas. Due to recent snow and how fresh these slides appeared, it is likely the new snow and wind triggered them. But, these also appear to be something like surface hoar or near sfc facet weak layer based on how the crowns look.
