Avalanche Forecast
Regions: Waterton, Waterton Lakes.
We are entering the spring mountain season. The main problems will be surface instabilities, daytime warming, and looming overhead cornices. The best skiing will be found on high northerly aspects. Unfortunately the ice climbing scene is grim with the exception of those willing to get their alpinism on.
Confidence
Moderate
Avalanche Summary
Numerous wet loose avalanches to size 1.5 observed over the weekend.
Snowpack Summary
There is a surface crust on all solar aspects and settled snow on polar aspects in the alpine. Generally the lower snowpack is well settled with the January drought layer down 50-130cm and a total tree line snowpack depth of 130-200cm.
At treeline a robust crust is on the surface.
Below treeline the snowpack is rapidly decreasing and partially buried hazards and unsupportive snow may exist.
Weather Summary
Warm and sunny Tuesday, cooling off on Wednesday with some snow. See photo for a more detailed 3-day forecast.

Terrain and Travel Advice
- Carefully evaluate big and steep terrain features before committing to them.
- Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
