Regions

Waterton Lakes, Waterton.

There is good skiing to be found at higher elevations in the Cameron Valley! Up to 40cm of snow now overlies the Christmas Crust Complex. Use caution near valley bottom where buried hazards still exist.

The coming warm temps and extreme wind may quickly build new windslab. Use careful evaluation when choosing your line.

Confidence

Low

Avalanche Summary

No new avalanches were observed today.

Snowpack Summary

5-10cm of snow being redistributed by light to moderate SW winds into windslabs in the alpine and at treeline. This overlies old windslab and a 2022-12-25 crust complex that is up to 30cm thick. Alpine and treeline midpack is well settled, below 1900m snowpack was saturated to ground by rain and has now re-frozen.

Terrain and Travel Advice

  • Be carefull around freshly wind loaded features.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
