Up to 20 cm of new snow now buries the Dec 11 surface hoar layer. This new snow, combined with light southerly wind, is building pockets of soft storm slab in the Alpine. The Nov 23rd surface hoar/crust/facet combo can be found down +/-100cm (SH is most prevalent in sheltered treeline locations) but has become increasingly stubborn in testing.
No new avalanches reported or observed.
There were several size 2 natural avalanches in the MacDonald gullies Friday, as well as MIN reports of easily triggered sluffs on all aspects and small skier controlled storm slabs in the Alpine on a North aspect.
