From the quote above it sounds like 2 feet of fresh is brought up as a good thing... which I can understand if you're worried mostly about rocks and wanting them buried. Note that 2 feet of snow is a lot, and would almost certainly make avy risk rather untenable. In general spring is a somewhat easier time for summitting since the snowpack has consolidated, is deep, and avy danger is generally lower and predictable... since the dangers are usually associated with daily changes... sun warming surface layers etc. Winter, and its snowpack of various layers, can be much more complicated. NWAC forecasts don't apply above Palmer on Hood. Not to say that reading the forecast doesn't help, but one needs to extrapolate for those areas outside the forecast zones, and that can only be done with a good background of avy knowledge. Good luck and be safe.
