Observer Comments
I saw recent avalanches on all aspects. I observed a recent R4 avalanche on W aspect of the hill dividing the summer and winter trails. The avalanche was snowmobile triggered and failed on a layer ~45cm deep, and propogated across most of the west aspect of the hill with slope angel > 30deg. I dug a handpit near the crown and found a pencil hard layer that failed on a weak 4F layer at ~45cm. I tracked this same layer of instability around to the N and E aspects at similar elevations where I did a full pit profile.
