Avalanche Summary

Two small avalanches were probably triggered on Friday by broken cornices in the extreme section of the Mur des Patrouilleurs on Mount Albert.

Snowpack Summary

Between 5 and 10 cm of snow covered the January 18 ice crust, which could be very thick (up to 9 cm) in some areas! This snow was moved above the tree line by moderate northwest winds on Thursday and northeast winds on Friday, exposing this icy surface in many places. Below the tree line, the new snow greatly reduces the feeling of skiing on glass.

Needless to say, travel in the alpine and on steep terrain is still perilous. With the snowpack still thin and many obstacles not yet covered, a slip on these icy surfaces could be disastrous. Spatial variability is important, from rock to ice to areas of greater accumulation. Generally speaking, the thickness of the snow cover varies from 50 to 100 cm depending on the sector and the altitude.
