Town obs: a few periods of intense rain in Hailey, one around 730, the other around 1400.
Tour obs, 1530-1830: Snowing S-1 to S1, snowfall was wet at highway level, mix of graupel and big stellars above. 1 cm accumulation during this time period. Tough to gauge HN, 2cm at highway, 6-9cm at 9,500', heavily wind drifted above. Brief clearing aroud 1600, with about 5 minutes of direct solar input. Clouds rebuilt shortly after and skies were overcast to obscured for the remainder of the tour. Winds blowing moderate out of the S/SW at middle and upper elevations. Rime forming on rocks and me at upper elevations.
Encountered drifts up to 30cm thick along ridgelines and in exposed middle/upper elevation terrain. All slabs I encountered were sitting on crusts and were stubborn to unreactive. Did not encounter fresh slabs on shady aspects, suspect they would have been a bit more sensitive. Classic ping pong ball skiing, good thing I was in the Boulders, exposed rocks helped me navigate.
At lower/low end of middle: ski supportable crusts existed on solars, ski pen was a bit deeper on shaded slopes, where I was penetrating 5-10cm into dryer snow, which produced some glopping issues.
Driving obs: saw a few fresh D1 slides from rain on steep, shaded, lower elevation slopes and a single D1.5. Suspect the problem may have been somewhat widespread, but visibility was poor and I didn't have much time so I wasn't looking terribly hard.
