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

Warm! Almost 40 degrees F. Calm. Overcast. About 60 cm of wet heavy snow.

Snow surface

60 cm of glue. The snow was fast and supportable for skiing. Trail breaking was boot top deep and tiring. Snowmachiners were having a very hard time.


We dug a full profile between Microdot and Marmot on a 20-degree west-facing aspect. See attached profile and on Avanet. We found 60 cm of new above a crust. Test showed ECTP26 resistant planer (not sudden like we initially thought), about 2cm above the crust on a what looked like a storm density change.
