More detailed information about the snowpack: 

Did the circumambulation of Mini Morrison today out of Convict Lake via Morrison Col.  Widespread patches of wind effect interspersed with areas of loose (probably blown-in) snow on top of windboard in all areas we saw today.  Witnessed snow being blown off the tops of the nearby peaks (generally by N winds), but wind speeds were calm or low at lower elevations except in the Col proper, which was a wind tunnel.  On the drive up, we saw some small fresh slides on Mt. Tom - probably point releases - but none in the area we skiied.  By 1130 we were starting small rollerballs from our skin track on a ESE aspect at 10800', but no other loose wet activity noted.  Snow quality on the descent was variable - the ankle-deep powder Mace, Huetter, et. al. exerienced yesterday coming down from the Col has been pushed around, leaving some deep piles and some scoured patches, which required strategy and forethought to navigate.  Skiing as chess match.
