Description of Snow, Weather, and Avalanche Conditions: 

Toured up Silver Peak this morning; coverage on the road decent, just had a handful of spots where we had to take off the skis to get over little creeks and bare spots. 31 degrees at the trailhead at 6:30 AM, warmed up quickly as we climbed out of the drainage and the sun rose. Skinned out the road to the east ridge of Silver, and then traveled up the ridge proper and slightly on to SE facing slopes. Snow surface was already wet and a bit slushy from 7300 - 8100 ft on E/SE facing aspects where the terrain was more sheltered from the wind. Snow felt supportable under our skis, but stepped out of my ski at 8:30 AM at ~8000 ft on an E/SE aspect and sank immediately to my bootop (photo 1; tested that several more times past that point, with consistent results). Above ~8100 ft and closer to the ridge top/summit, winds were much stronger (SW winds, gusts ~30 mph) and were helping keep the snow surface cool and firm. Observed wet slide debris on the E-face of Billy's (photo 2; looks like triggered around the base of the rock face, maybe from some cornice drop). Skied most of our ascent route back down, with slight deviation onto a NE slope at 7600 ft; snow was supportable, but quite variable (firm in the shade, wet spring snow where the sun had gotten to it). Skied another NE facing slope back down to the road from 7400 - 6770 ft, which was quite variable and mostly unsupportable on skis by 9:45 AM.
