Weather

Sunny with moderate winds above treeline. It was very warm near treeline where there was not much wind. It was colder above treeline with the sustained winds.

Snowpack

I experienced numerous collapses but they were minor due to the shallow depth. The layer collapsing was a layer of wet snow above a shallowly buried melt-freeze crust. The 4 to 6 inches of moist snow was forming a slab. Although I got cracking and collapsing on steep slopes, I did not trigger any avalanches. The location of these collapses was east and southeast-facing slopes near treeline. ---On a north-facing slope near treeline I found a snow depth of about 2 meters. Five inches of dry, new snow was sitting on top of a knife-hard, thin melt-freeze crust. There is dry snow beneath this crust. It seems like it would take cloudy, mild conditions and warm nights to cause a wet problem on these due north-facing slopes.---On a near treeline east-facing slopes there was 6 inches of moist to wet snow over a softer melt-freeze crust. Beneath this crust is another 10 inches of soft melt forms. If the upper crust melts we could see larger avalanches gouging into older, soft snow. There is a knife hard ice crusts (previous frozen melt water) 16 inches from the surface.---I didn't see a snowpack structure conducive to wet slab avalanches. Loose wet avalanches continue to be the main threat although this is trending down with Monday's wind and clouds.
