Quick report

On my drive to Carson Pass, I saw signs of unstable wet snow, including a pile of wet loose debris on the southbound lane while going around Emerald Bay. So it came as no surprise that large pinwheels and sluffs of wet snow released as soon as I kicked my first test slope on Red Lake Peak. NE-E-SE aspects all had deep wet snow on them up to the summit of Red Lake Peak (10000 ft). Many of these slopes also had roller balls or pinwheels on them from yesterday, and some had fresh ones from today. I found a small cornice to test on my way up the ridge. It broke with a gentle kick from my ski, even though it was already slumped over and eroded by the NE winds. I saw several other larger cornices but stayed well away from them. 

When I moved over to the wind-swept SW-W aspects, the snow remained ski-supportable until about 1:30 pm, especially on the W aspects above 9400 ft. Below about 9200 ft, I started sinking into my ankles while on my skis on these aspects as well.  

I saw debris from another wet loose avalanche covering the entire southbound lane and most of the northbound lane of Emerald Bay Road at 3:30 pm. 

I saw debris from two wet loose avalanches on Emerald Bay Road, one on the way to Carson Pass (D1) and one on the way back (D2). I also saw wet loose avalanches on Tallac and the East face of Jakes. Ski cuts on NE-E-SE facing slopes triggered wet loose sluffs, pinwheels, and roller balls.
