A reminder to use good travel techniques like spacing out or skiing a line one at a time if you are stepping out into bigger and more serious terrain.

Summary

Confidence

High

Avalanche Summary

Sporadic avalanches are still occurring throughout the region. On Tuesday a size 2 avalanche ran in the Churchill North Slide path to tree line.

Don't forget to post avalanche observations to the MIN.

Snowpack Summary

Sun crust at all elevations on solar aspects. Unsupportive facets on polar aspects in shallower snowpack areas. Basal facets and depth hoar make up the base of the snowpack. Snow depth varies ranges from 60-170cm.

Terrain and Travel Advice

  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
  • Watch for unstable snow on specific terrain features, especially when the snow is moist or wet.

Problems

Loose Wet

An icon showing Loose Wet

Watch out for increased solar input or rising temperatures. When this happens wet loose avalanches will likely initiate from steep rocky terrain on southerly aspects, and may be large enough to trigger deeper problems.

Aspects: South East, South, South West, West.

Elevations: All elevations.

Likelihood

Possible - Likely

Expected Size

1 - 1.5

Deep Persistent Slabs

An icon showing Deep Persistent Slabs

The bottom of the snowpack is inherently weak with well-developed Facets and Depth Hoar. Large triggers like cornices, and wet avalanches can step down to this deep persistent slab, present on all aspects, TL and above.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood

Possible

Expected Size

1.5 - 3.5
