|Location:||Independence Mine / NW Aspect of Marmot|
Route & General Observations
Went for a tour aiming to get up the bench between N aspect of Marmot and Microdot, while opening track, we had a lot of whoomphing and propagation, with a remote “slide” compressed in a small slope.
Turned around and went to have fun in other slope by the mine.
Obvious signs of instability
|Recent Avalanches?||Yes||Collapsing (Whumphing)?||Yes||Cracking (Shooting cracks)?||Yes|
Whumphing while approaching and opening track. Propagating underneath.
A 32º slope had a collapse into a 21º convexity, it didn't propagate as slide, but created shooting cracks and compressed snow in the lower angle.
Sunny and clear skies, no wind.
2 to 0 º C Air Temps.
I got cloudy later in the day.
Supportable crust on top of sugar at the very base.
Early season bed surface.
Informal pole tests. No snow pit in that route.
