Written Report:
There was 25cm of new snow at Three Creeks Lake this morning, but it was hard to keep track of it as a strong west wind blew it all over the place. The variation in wind deposits was extreme. Some areas were scoured down to yesterday's rain crust, most areas had 15cm and some pockets had 100 cm of loading!

I dug on a ENE aspect with 90cm of windloading at 7200'. The new snow was bonding to the rain crust well, however, I got sudden collapse results in the still wet/weak snow just BELOW yesterday's rain crust. The wet snow from Sat AM crusted over, but still hadn't fully set up by midday today. I think it would difficult to trigger that wet layer, but a rapidly building windslab on N-E aspects with warming temps in the short term could be enough.

The windslab was a consistent (1F) density, the rain crust was (P) and the wet grains below were (4F)

In the attached pics, you can see the windloading with Saturday's rain crust way down there...
