Snowpit Observations
More detailed information about the snowpack: 

I wanted to see how the new snow was bonding on old wind/melt freeze crusts in the Mammoth Rock area.  Also wanted to see the extent of faceting going on underneath the snowpack.

Pit was at 9080', N/NE.  HS220, HN31.  Air temp 1 degree C and warming.  Ski Pen 23, boot pen 41. Skies broken, with surface temp at -5 degrees C.  Facets ranging from 1-2mm in size were found throughout lower layers.  Profile attached.

CT yieled interesting results, CT23 and 27 on a lower faceted layer, (SC/Q1).  ECTN2 on upper layer, ECTX on the deeper layer, just shy of a meter deep, but I would think if something large enough was to trigger it could be worrisome.

On the descent roller balls were forming, snow was getting progressively stickier.
