Snowpit Observations
More detailed information about the snowpack: 

Went for a skin up to Mammoth Rock to check out conditions.  There was a skin track, likely from earlier in the day, that was partially blown in by the wind transport. 

Sections of trailbreaking were deep and challenging.  Moderate wind from the SW was starting to form a wind skin near Old Mammoth Road.  As we made our to the bench below Mammoth Rock, there was obvious moderate wind transport on the ridges/rollovers above us, carrying snow down leeward slopes.  We did our best to stay towards the ridge on the left, away from these slopes just in case something moved above us where there was rapid wind loading occurring.   We stopped just shy of Mammoth Rock as the wind skin started to thicken to a soft, variable depth wind slab.  

We skied the line of the skin track back to the car.  The skiing was so deep we could hardly turn or enjoy the pow.

Some small cracks were observed around our skis, but no other obvious signs of instability.  We used two small rollovers as test slopes.  Kicking, stomping, and then jumping on these test slopes did not result in any visible cracking or movement in the snow.  Curious what the snow would have looked like if we had gotten above Mammoth Rock.

Any other comments about the observation or links to outside pages that have more info on the observation: 

We noticed that areas near bushes and trees/treewells seemed pretty sketchy with the large new snow accumulation
