Avalanche Summary

Numerous natural dry and wet loose avalanches to size 2 were observed this week. A few natural slab avalanches to size 2.

Snowpack Summary

20 cm of new snow with a thin surface crust on solar aspects. Below the new snow a thick melt freeze crust exists at all aspects and elevations. Below this, the snowpack is moist to ground at treeline and below, now slowly refreezing. The Dec 23rd and basal crusts are currently less of a concern due to the effect of significant warming last week and anticipated refreeze. Significantly less snow in the eastern areas of the park. Snowpack depths between 30 - 150 cm.

Up to 10 cm of new snow overnight, clearing through the day. Light NW winds, alpine high of -8 degrees.
