AVALANCHE ACTIVITY:
An avalanche in Iceland has damaged infrastructure and equipment at Siglufjordur Ski Field.Avalanche Summary
A few small wind slab avalanches have been reported since the weekend. Explosive control targeting cornices on Friday and Saturday 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.
Snowpack Summary
Extensive wind effect in the alpine includes scoured windward aspects and hard slabs in lee terrain. Soft snow may be found in sheltered areas around treeline. 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. Several large natural and human triggered avalanches failed on this layer earlier this month. Although it still shows propagation and collapse to moderate to hard loading in the most recent snowpack tests, it has become well bridged by overlying snow and crust.
Just for the record:
