Observer Comments

Observed evidence of old slab and dry loose avalanches that appeared to have released during the last storm. None of the crowns appeared to have stepped down to the thanksgiving crust and were all in the new/old snow interface.

Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.

Clear skies all day with dense valley fog building after noon.
Calm winds and brisk temps in the mid-low teens all day.

Snow surface

Beautifully preserved stellars and new snow depths ranging from 50-75cm of stupidly dry and low density blower powder!


We dug two pits at 2875' on a SSW face of sunburst. Grains surrounding the thanksgiving crust showed bonding and a distinct lack of faceting
Crust in this location was still relatively stout being ~5cm thick
Pit 1:
ECTN17 Q3 BRK 50cm from surface within new snow in a strange layer that showed a distinctly different orientation of the stellars looking very glittery
ECTN24 Q3 NP 75cm from surface on new/old snow interface (old snow being 1F hard old wind slab)
