Observation: Turnagain
Location: Sunburst
Standard up track to 3200′. Checked out new snow depth, wind effect and snowpack structure.
Obvious signs of instability
Observer Comments
Whumpfing near our pit location at 2300'
Weather
Partly sunny, getting progressively cloudy throughout the day
Light west winds
Temps in the 20s
Snow surface
Soft new snow 3-5"
Light wind effect/dappling starting around 2000'
Stiffer snow near the ridge
Snowpack
Depth was variable but averaged around 3' settled snow. We were hunting for the buried surface hoar that was buried on 11.20. The interface is easy to pick out and surface hoar was found but was not reactive at all. Our layer of concern was the facets at the base of the snowpack. Pole probing all along the route went from softish snow to stiffer snow then and dropped in the facets. We dug 6 pits total. The facets were most reactive at 2300': ECTP 7, ECTP 12 and CTs were failing on isolation or with placing shovel on the block. 2900':CT 14, CT 16 ECT 17, ECTX. 3200': CT 11, CT 20. Sunburst is a bit tricky finding spots that were not previously skied which we tried to do with our 3 locations. There is definitely a slab over a weak layer that could be an issue for a while.
