Regions

Yukon, Tutshi, Wheaton, White Pass East, White Pass West, Haines Pass.

Low danger is a great time to explore complex terrain.

Evaluate steep lines for small wind slabs that may knock you off your feet.

Confidence

High

Avalanche Summary

In periods of low danger, avalanche activity is unlikely. Continue to practice good travel habits.

There have been no recent reports of avalanches.

Consider submitting to the Mountain Information Network if you have been in the backcountry.

Snowpack Summary

Wind has redistributed recent snow, forming pressed surfaces and wind slabs in open terrain while leaving 15-30 cm of soft snow in sheltered areas. A breakable melt-freeze crust covers most solar slopes.

A buried surface hoar or crust layer, 40 to 60 cm deep, is variable in distribution and has produced some test results but no recent avalanches. Similarly, a December crust with facets, 100 to 150 cm deep on all aspects up to 1750 m, has shown no recent activity or significant test results.

Snow depth ranges from 100 cm at highway elevations to over 300 cm in the alpine.

Terrain and Travel Advice

  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Carefully evaluate big and steep terrain features before committing to them.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.

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.
