Waterton Lakes

15-20 cm of new snow fell at Cameron Lake over the weekend. There is decent uphill travel and skiing to be had due to the burly crust that sits underneath. Watch out for fresh wind slabs on all aspects as this snow blows around with variable wind directions through the week.

A few natural dry loose and wind slab avalanches to size 2 were observed on Sunday.

20 - 40 cm of snow fell over the weekend and sits on a crust 10-15 cm thick at all aspects and elevations. Below this, the snowpack is moist to ground at treeline and below. This will slowly refreeze with cooler temperatures this week. 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.
