Roller balling noted on NNW slopes below 9k. Dug in wind zone. 100' below was soft snow surface. wind slabs isolated to skis on this slope breaking up before going anywhere. Deteriorating wind slab with sastrugi on the surface.
Small soft slab avalanches 4-6" deep running in the new snow on a density change 2" off the ice crust. Easily triggered with skis and on steeper slopes ran naturally during periods of increased PI rates. Impressive 2" an hour snowfall during tour.
