Snowpit Observations
More detailed information about the snowpack: 

A cloudy day in the morning, with moderate to strong sustained winds out of the west.  A mixed bag of conditions out there from scoured slopes with inverted tracks to bullet proof hard slab,  breakable crust and chalky skiing.  We were up in the alpine today looking at the persistent slab problem.  Mixed results, with more easterly slopes seeing that facet layer healing.  You're able to clearly see the layer, but stability tests are indicating that this aspect is healing.  Northerly aspects are not healing as quickly with test scores of ECTP 13, 11, 17 and 19 all sudden planar.  These slopes did not have facet crust combination and do not see any sun with any regularity.  PST results were anywhere from 50 / 62 END SP.  Tests on north facing slopes were done on slopes 40 degrees or steeper.  Warm temps from the last couple of days have produced a melt-freeze crust at low and mid elevations on all aspects. 

Photo 1: Loose granular snow that was being blown from the windward slopes today and made for decent turns on a firm bed surface.

Photo 2: Breakable wind crust to bullet proof firm on a N aspect

Photo 3:  Snowpit on a NE  aspect around 12,600' with wind slab taper.

Photo 4: Snowpit on a N aspect around 12,200'

More detailed information about the weather: 

Snow was moving but it was loose granular snow that was not forming a slab.  WInds were moderate to strong out the west.  Skies were cloudy in the morning but the sun came out in the afternoon.  Temperatures seemed to warm with the presence of the sun but things were staying locked up above an near treeline.
