Reported on avalanche.ca and on the Columbia Valley SAR Facebook that they responded to a recreational snowmobile accident today. 2 involved, 1 fatality.
Size 3/crown 40-100 cm/2 m burial
From today's bulletin:
"Friday's reports show the weak layers, up to 80 cm below the surface, were reactive to explosives, skiers, and naturally. Sizes were between 2 and 3.5. Additionally, there are stories about whumpfing around moraines. Explosives targetting the deep persistent layer at the bottom of the snowpack released several size 3.5 avalanches up to 200 cm thick.
Search and Rescue responded to a serious incident today, Saturday April 15, in the Thunderwater Lake riding area: a rider triggered size 3 avalanche on a southeast facing alpine slope with a crown 40 to 100 cm thick.
Thursday's avalanche reports spoke to the continued storm slab or persistent slab avalanche problem (previous dry snow above crusts or facets from April 7 or March 31) with several avalanches to size 3.5, many seemed to release with daytime warming. Some were cornice triggered."
