Regions

Glacier.

Great skiing can be found, but be cautious of wind slabs in immediate lee features, as well as dry, loose avalanches from your own sluffing.

Enjoy the longer days of Spring. This is when the best skiing is had...just don't let the secret get out!

Confidence

Avalanche Summary

Dry, loose avalanches up to size 1 were noted from steeper terrain (>40 degrees) on NW through E aspects.

A widespread, natural avalanche cycle occurred up to size 4.0 on Mar 19-20 during the atmospheric river. Check out pics from the recent mega avalanche cycle in the MIN Reports. It shows some of the huge debris piles that are making travel challenging.

Snowpack Summary

Gusty winds have created wind slabs in exposed terrain, while sheltered features hold dry, loose snow lying on a firm crust. South through West aspects may have a surface crust on steeper slopes.

Below the storm snow, a strong crust exists up into treeline. Another crust from early March is down 70-150cm.

Travel can be challenging below treeline with frozen tree bombs and huge avalanche debris from last week's super storm.

Weather Summary

Sun and cloud with isolated flurries.

Tonight Scattered clouds. Alpine low -12°C. Ridge wind SW 10-20km/h. Freezing level (FZL) valley bottom.

Tues Mix of sun and cloud. High -5°C. Wind S 10-25km/h. FZL 1500m.

Wed Cloudy, isolated flurries, trace amounts. High -3°C. Wind 10-30km/h. FZL 1800m.

Thurs Flurries, 5-10cm. High -3°C. Wind N 10-20km/h. FZL 1900m.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Keep in mind a buried crust offers an excellent bed surface for avalanches.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.

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.

Loose Dry

Loose Dry avalanches are the release of dry unconsolidated snow and typically occur within layers of soft snow near the surface of the snowpack. These avalanches start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-dry avalanches include point-release avalanches or sluffs.
