Snowpit Observations
More detailed information about the snowpack: 

Toured from parking at Aspendell, crossing a variety of snow and aspects. No cracking or whumping noted during entire tour. Light west wind and clear skies at start of tour.

Southeast facing slopes above Aspendell, up to 9400 ft elevation showed melt freeze crust.  Snow was beginning to melt by 915am.  No signs of instability or avalanche activity on these slopes during ascent or descent (315pm).

Northeast facing slopes from 9600-10400 ft were mostly wind affected.  Some powder still hiding in protected areas. Ski penetration ankle deep.  Hand pits dug on these slopes showed no failures even with a hard amount of force. 

Conditions in the north couloir (11400ft-13000ft) were variable.  Wind crust ranging from 2-5cm thick, with 20-40 cm of unconsolidated, fist hard snow underneath.  Boot penetration from ankle to knee deep.  Several hand pits were dug during the climb of the couloir.  The wind crust on the surface often failed on isolation, with snow underneath appearing well bonded.  A series of 3 creep cracks exist at the base of the couloir, large enough to injure a skiier.

Weather at 13000ft, at 2pm was light wind from southwest with a small amount of snow transport (mostly spindrift) into the north couloir.
