AVALANCHE ACTIVITY:
An avalanche has killed a ski tourer near Bauges, France. Article below. Net PicLooks very wind affected. in most of the backcountry.
Avalanche Summary
Explosive control work targeting cornices on Thursday produced size 1.5 results and did not trigger slabs in the slopes below. This indicates an improvement in stability since last weekend, when similar work produced size 2 results, some triggering deep slabs on the rocky slopes below.
Earlier this month, we saw significant deep persistent slab activity, both natural and human triggered. Deep glide cracks have also been observed previously but appear to be holding together in the cool temperatures.
Snowpack Summary
Extensive wind effect in the alpine includes scoured windward aspects and hard slabs in lee terrain. As wind slabs facet and lose cohesion in the cold temperatures, they have become largely unreactive. A widespread surface crust exists below 1900 m and on south-facing slopes.
Remnants of a melt-freeze crust from early December may be found around 200 cm deep in the snowpack. In thin rocky snowpack spots, it still shows some propagation and collapse to moderate to hard loading in the most recent snowpack tests. In thicker snowpack areas it has shown no results, and appears to be trending dormant... for now at least.
