Trigger a small wind slab (0.5) near ledge mountain. We were trying to stay away from lee slopes. Lots of wind at and above tree line. Significant snow transport from the peaks. Didn’t get a picture cause it was too cold.

Snow conditions were: Wind affected, Powder. Weather conditions were: Cold, Windy. We rode: Alpine slopes, Steep slopes.

Avalache Conditions: Slab avalanches today or yesterday. Whumpfing or drum-like sounds or shooting cracks.


Isolate wind slaps present on NE slopes. Stayed away from W slopes as there was a lot of snow beeing transport


The slab broke in an area of obvious wind loading just below ledge mountain
