Snowpack Summary

The top 30cm remains unconsolidated except where exposed to wind where soft slabs have been formed. The snow depth is variable at all elevations. There is a crust/facet layer distributed through the region in the mid-pack with mixed reactivity and a weak basal facet/depth hoar layer at the base of the pack.

Avalanche Summary

Friday's field trip to Pyramid mountain area noted nothing new and no signs of instability and a consolidated snowpack. Thursday's field trip to Churchill slide path noted no new naturals. Wednesday's trip to Parkers Ridge noted several loose dry up to size 2 out of steep, rocky solar terrain triggered by solar input.

Confidence

The weather pattern is stable

Avalanche Problems

Wind Slabs

Wind slabs are present on lee slopes and cross-loaded features

  • Use caution in lee areas. Recent wind loading has created wind slabs.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 3

Persistent Slabs

Isolated to very specific sheltered locations at treeline.

  • Dig down to find and test weak layers before committing to a line.

Aspects: All aspects.

Elevations: Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2

Loose Dry

Specific to steep terrain. Ice climbers should pay particular attention to this as entrenched loose snow may have the volume to knock climbers off their stance. Solar input has the potential to trigger this problem.

  • Be increasingly cautious on sun exposed slopes.
