A small whumpf in the skin track was followed by a massive one a few minutes later. I can count on one hand the number of times I got whumpfs in a skin track...rare indeed. The second one was so big it had us both deeply concerned. We peeled off the skin track after deciding to not cross a gully and soon found debris from a sizeable avalanche that released a couple days ago about 500' above us. We dug in the flank and had 100cm of snow, 60 cm new from last week. The snowfall during the Avalanche Warning, doubled the depth and more than doubled the snow water equivalent of the snowpack. It was a large load and avalanches are breaking underneath the new snow.
Karl was using his 100 cm long Norwegian Battle Saw (pic)...a bit overkill.
