Avalanche Grand Couloir

Size 0,5-1 avalanche probably naturally triggered from a wind slab formed during the last storm.

From 830m to 750m: crust with lateral loading up to 20cm on top of crust. No reactivity on the way down. From 750 down, 15 cm of new/transported snow on top of the last storm. New snow was loose and snowpack underneath was pretty cohesive. Amazing conditions under 750m.
