Avalanche Summary
One size 2 loose, dry occurred today in the alpine on an East aspect on Mount Murray (looks like it was solar radiation triggered).Several other loose dry size 2 were observed on the East End of Rundle and in the Bow Valley on solar aspects
Snowpack Summary
On the surface, we have about 15cm of loose dry snow. There is isolated wind affect, mostly in the alpine, just below large cliffs and isolated pockets near ridge lines. The sun had some punch today which triggered some loose dry avalanches on solar aspects. The weak basal layers are still there, and as unconsolidated as ever. What is saving us from a nightmare of a snowpack is the mid pack bridging effect. The mid pack has enough strength and depth that triggering the bottom layers is becoming more difficult. The key to avoiding trouble is avoiding thin areas where the bridging is minimal.
