Regions

Waterton Lakes, Waterton.

Good ski quality in the Cameron Lake area, especially in more sheltered areas. As always at this time of year watch out for early season hazards like stumps and rocks. The wind has returned over the last two days, pay attention to newly formed windslabs.

Confidence

Moderate

Avalanche Summary

One size 1.5 windslab avalanche observed on a road patrol on Rowe Ridge. Otherwise no new avalanches.

Snowpack Summary

The snowpack is 80-120 cm deep at treeline and consists of settling early season snow. Exposed lees have up to 40cm of soft windslab that was reactive to compression tests however no avalanches observed. There is a melt freeze crust 10-20cm off the ground that is about 1cm thick. So far, no weak grains observed near this layer and tests showed no result.

Weather Summary

Tues

Wed

Partially cloudy with no precip expected. Alpine highs near -5 with moderate to strong SW winds.

Thurs

Partially cloudy with no precip expected. Alpine highs near zero with moderate to strong SW winds.

Terrain and Travel Advice

  • Wind slabs are isolated, but may remain reactive.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.

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.
