Snow Characteristics Comments: 

Lots to choose from out there!  Clear night with cold valley temps led to surface hoar growth in the low areas around the creek.  Flat and northerly facing areas held weak loose surface snow; by far the best skiing of the primarily south-aspect tour was in the out track-zone along the trail where some faceting had occurred and neither wind nor heat had played spoiler.

 Skinning up a south aspect ridge--and thus rolling between a squeezably-wet surface on SSW and dry snow under a breakable wind slab to the ESE--was a case in point for skin wax.

Coming out a scrubby south facing gully took me back to skiing as an 8-year-old lock-kneed snow-plower: graceless transitions from melt-freeze crust through a small strip of lovely loose and then onto breakable wind crust .  Pretty dang fun, really.


Good visibility for looking at older avalanches:

The first avalanche presumably came down on the morning of 12/16: loading up high brought snow down through a lower-elevation track where it entrained snow that had soaked up plenty of recent rain.

The second presumably occurred after the Christmas storm: on the 27th high winds blew from the SSE across Bunnell's ridge and might have transported the new snow unto the north side.  The would-be slide cracked wide (over 100 ') but didn't appear to make it throught the wall of trees into the steeper slopes below.

The 3rd set of avalanches--minor loose sluffs running on steep terrain--speak to the weak surface snow.  We saw most on South aspects but that could be a function of our view: East and North East also had sluffing.  Nothing that we saw stepped down into a layer below.
