Plan a safe day out in the park, by avoiding hazards from cornice fall and the many lurking crevasses on our glaciers.
Use caution on solar slopes where a sun crust in present down 10-30 cm. Riders have triggered this crust in the last couple days, creating avalanches up to size 2. Watch for sluffing on polar aspects.
Wednesday a skier triggered a size 1 on a SE asp, in the alpine behind Mt Bonney. This was a thin slab above a crevasse failing down ~15 cm.
Also on Wednesday, a natural avalanche sz 2,5, possible cornice fall off Mt Bonney, MIN.
Two moist snow skier triggered avalanches on Tuesday at the top of avalanche crest. These were sz 1.5-2, triggered on a sun at the bottom of the recent storm snow down ~15cm.
A cornice failure from above caught a person on Cheops N 1 today, knocking them downslope ~300m.
A field team around Lookout Col/Ravens area was able to ski cut loose surface sluffs to sz 0.5 in steep terrain.
Expect a surface crust on solar aspects and dry snow on polar aspects. 15-20cm of settled snow is covering the March 31st which is a a solid crust on solar aspects and isolated surface hoar/facets on polar aspects.
The mid and lower snowpack is generally strong. However, the basal weakness from November can still be found near the ground in many locations. This layer will remain a concern until the end of the season.
