Carefully assess for changing conditions - unstable, spring weather can deliver highly variable snow amounts or periods of strong sun, which can increase avalanche hazard locally.

Confidence
Moderate
Avalanche Summary
No recent avalanches have been reported in the region.
If you head out in the backcountry, let us know what you are seeing by submitting a report to the Mountain Information Network.
Snowpack Summary
Recent snow overlays variable old surfaces, including a hard crust on solar aspects and lower elevations. Wind slabs persist in exposed lee terrain.
The mid snowpack holds several persistent weak layers including layers of surface hoar in wind-sheltered terrain and old crusts on south-facing slopes. No recent activity has occurred on these layers.
The lower snowpack is made up of a widespread layer of large, weak basal facets and depth hoar in areas. Neighboring Kananaskis Country reports continued avalanche activity on this layer. Avoid thin and rocky areas where this weak layer is more likely to trigger.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Avoid thin areas like rock outcroppings where you're most likely to trigger avalanches failing on deep weak layers.
- Make observations and assess conditions continually as you travel.
Problems
Wind Slabs
Recent new snow and wind has formed wind slabs in exposed lee terrain.
