This slope has avalanched earlier, probably during the rain in snow event March 9-11. Leaving an ice layer at ground of about 2.5cm. The profile above was on top of that layer and all recent snow/ windrifted snow. Other areas had snow depths of 35cm to 90cm

3 N gullies were observed to have avalanched most likely wet slides during the March 9-11 rain cycle. Sizes were from D2 to D3. 

Soft slabs that were non reactive and loose snow was observed. Very small sloughs were triggered on downhill. Small slab releases were only observed in the skin track and on hand pits in isolated areas. 

After sundown on the exit there was clear skies and very cold temperatures. We observed surface hoar developing in open in sheltered areas.
