Quick report

Cracking
specific

Northwest wind changed conditions rapidly overnight (20-30 mph JHMR Summit). There was a large amount of low density snow available for transport from previous 24 hours (7-8% density JHMR). Fresh wind slabs were reactive primairly in the upper elevations. Multiple small avalanches were triggered on wind loaded pockets. One larger slab (D1.5) released previously off the Gang Plank at 9,000'  E aspect on a very steep slope  (unknown trigger with tracks adjacent). A couple small crowns were visible on easterly aspects of the Poop chute that failed in last ~48 hours naturally. 

It's worth noting that NW wind is NOT the predominant wind direction for our forecast area and abnormal terrain may be wind loaded. 

Scattered to broken cloud cover and cold temperatures kept snow surfaces cool all day. Sheltered terrain contained low density, blower powder. 

Signs of instability on upper elevation wind loaded terrain (Northwest wind) with recent avalanches, shooting cracks, scoured surface, and large pillows/drifts.

Snowpack

Dug in the middle elevations on a N aspect to assess the Christmas crust where the overlying slab is shallower. Did not find anything of concern in this location. The bottom 70cm of the snowpack was comprised of wet snow where all the previous crusts have morphed together. 

On Taylor, Christmas crust was buried 50-60cm on SE aspects. Crust exists up to between 9,000-9,200'.
