Quick report

Comment
Skied between 1300-2500m on SE-SW aspects. We observed several whumpfs in open areas at the low end of treeline, so we dug down and found facets over a crust down 60 with sudden compression test results in the moderate to hard range. Also did a couple of extended column tests which propagated at moderate to hard as well. Sticking to lower angled slopes we gained a ridge at 2500m in the pm where the wind was moderate from the south and very chilly!

Avalanche report

Comment
Saw one natural slab avalanche out of steep alpine terrain that we suspect failed on a persistent weak layer. Looked like either a dry loose or cornice ran down and triggered the slab. It was hard to tell the age as there was a few recent dry loose over the debris, but it looked new.
