none. New powder snow was so light it didn't need to bond to anything, so easy sloughing on descents.
Observation: Hatcher Pass
Location: Fairangel
Toured from Independence Mine lot up to Fairangel, exited via Archangel XC ski trail.
Observer Comments
Weather
clear morning, cloudy afternoon. calm to very light winds in the bowls, 5-15mph easterly winds when within 100ft of ridge tops.
We noted very active snow plumes off of all ridge tops above 4000ft all day. See picture of Marmot for example. Other ridges with noted spindrifts all day are: 4068, Microdot, Rae Wallace, Skyscraper, Idaho, Delia Creak ridge. There was definitely a lot of snow available for wind transport, and it was being moved all day, there will be slabs.
Snow surface
very very light powder, 4-8", a few areas were 10-15" Ridge tops were being blown clean through out the day.
areas back around Dogsled Pass looked really thin, very little snow back there.
