After triggering the small avalanche, the snowmobilers avoided the slopes most exposed to the wind.
We therefore understood that wind slabs were going to be reactive in this area, writes one of the snowmobilers in her report published on the organization's website, adding that they did not snowmobile on slopes. most exposed to the wind to avoid triggering a larger avalanche.
In the mountainous region, north of Vancouver, Avalanche Canada reports that there had natural avalanches Friday and Saturday: Rain and mild temperatures impacted the snowpack on mountain tops, forming wet, deep snow at lower elevations.
Further east, in the greater Rocky Mountain region, avalanches are deliberately caused. Areas of Glacier National Park in the Selkirk Range are closed for preventative avalanche triggering using explosives.
Warming, fresh snow and winds are the perfect ingredients for new slabs to form.
A quote from Avalanche Canada
Avalanche Canada adds that natural avalanches have occurred in this park, notably at Mount McDonald, and that skiers triggered avalanches at Mount Cheops on Tuesday and Thursday. All avalanches [were] triggered by skiers [who] slid on a crust of sun.
