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.

Observer Comments

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.
