Snowpit Observations
More detailed information about the snowpack: 

Toured from Propane tracks up standard route to Punta Bardini.

Morning clearing with broken skies allowed observation of wind transport at ridge tops as well as down low in treed terrain. HST averaged 25cm with drifts up to 50cm. Snow was not as slabby as expected, with 4F wind affected snow atop F comprising the HST.

All observation points from exposed slopes near skier's left Tele Bowl all the way up to 9900' below Punta Bardini highpoint showed buried surface hoar up to 4mm. Kick turn tests, handshears and compression tests (CT1 SP down 28cm) identified this PWL. Tried to take a photo of the well-preserved SH crystals, but wind kept blowing them off my card! Not much of a slab sitting on top of it anywhere, so ECTN3 was not surprising, and SH layer is still shallower than ski pen in most locations, but will be interested/concerned to see this loaded with the incoming new snow.
