Avalanche: Hatcher Pass

Hi Allie. Brint, Austin, Phillip and I went up between Microdot and Marmot where we dug a full pit. Then we went toward Hatcher Pass. Please give me a call if you need more info Allie!
Avalanche Details
Wet loose avalanches released on steep southerly aspects of Skyscraper during a short sunny spell in the early afternoon. These D2 avalanches sometimes started shallow slabs, about 30 cm thick.

Observer Comments
Rapid warming, recent heavy precipitation, recent avalanches. See avalanche observations on Avanet.
Weather
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.
Snowpack
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.
Avatech CEO Brint Markle examines the propagation 2cm above the crust.
