Wet snow avalanches on Incline Lake Peak

Several point release avalanches occurred on 35-40 degree SE-S facing aspects yesterday and today. Some of these occurred naturally and some were skier triggered. On 35-37 degree test slopes today, ski width wide sluffs occurred in response to ski cuts on SE facing slopes between 8600 and 9200'. The failure layer for these slides was the interface between the older melt-freeze crust and the recent new snow. Skier triggered whumphing and collapsing occurred this same failure layer on near by 30-32 degree, SE facing slopes. The snow on the sun exposed aspects melted and softened quickly today as the sun hit the slopes. Several inches of saturated wet snow existed on the sun exposed SE-S-SW aspects by midday. On the northerly aspects, any areas that received any amount of sunshine had wet, sticky snow on the surface which quickly refroze into a thin crust once the sun left the slopes.
