Snowpit Observations
More detailed information about the snowpack: 

Dug a quick pit at 11,400' today above George lake on a NNW aspect. Average of about 90cm of snow over a slope with lots of rocks. surface snow was fist hard then 4F hard by 5cm down. By 10cm down the snow was 1F trending towards pencil hard pretty quickly. The new snow was all nice and rightside up. Unfortunately the bottom 25cm of the snowpack was gross, LARGE grained facets. We did not notice a crust layer seperating these two layers.

This big chuncky slab sitting over gross facets did not inspire us with confidence. 

We saw a little avalanche crown in the complex, rocky and shallow north facing terrain on the George Lake Ridge that looked like it released in the wind event. Didn't look more recent than that. 

Additionally the conditions were quite variable, with soft surface snow giving way to wind slab in the middle of a turn. The snow underneath the soft stuff wasn't always supportable and we would punch deeper into the snow occasionally, leading to some very difficult skiing conditions. Down lower approaching Sabrina in the trees the snow was very punchy and variable. A few good, soft turns that almost felt like powder would lead into heinous crust that would try its best to take you off your feet. However the snow does seem to be giving the rocks a nice coat, so even though there isn't much snow covering the rocks I was jumping around and did not actually scrape rock more than once or twice. 

Any other comments about the observation or links to outside pages that have more info on the observation: 

With little snow, we were able to follow the trail almost all the way up into the drainage... There is definitely snow down here and I am having a good time, but everything is so thin, and with the sketchy snowpack structure the big lines aren't in yet.

The George Lake Ridge was pretty scoured. If you were really motivated you could maybe scrounge some lines together, but the cover is really thin and the riding would most likely be difficult and punchy wind board with questionable structure.

Started off today around 0745-0800 looking at dark and stormy conditions with a little bit of snow flying. As the day progressed the clouds lightened up, and we spent most of the day in the sun with about 40% of the sky covered. Gusty, but we saw very little blowing snow on the ridges. Temps were warm when there weren't gusts, and heading back across Sabrina at 1500 was hot and sunny. No snow accumulated today.
