- I ski cut from the trees above the break over towards the trees in the center of the crown. There was a big settlement. Slab had a clean propagation across the entire slope. The crown broke 2m above me, but I managed to hang onto the tree. The avalanche ran on a very pronounced crust layer, I think from mid-January.
