Regions: Glacier.

Dig down and look for the buried persistent layer before committing to consequential terrain.

It's still cold out! be sure to pack extra layers in case of emergency.

Moderate

Avalanche Summary

Natural avalanche activity has eased.

Neighboring operations are reporting rider & remote triggered avalanches on the Jan 30th layer.

A sz 2 wind slab was triggered by a skier part way down Forever Young, resulting in injuries.

A sz 1.5 wind slab on the Ravens was observed while flying to the above accident.

Snowpack Summary

Funky variable winds have caused widespread wind effect. This wind effect is most prominent in the alpine & treeline but does exist BTL in areas affected by localised valley winds.

20-40cms of recent storm snow has buried a weak layer of surface hoar, facets and/or suncrust (Jan 30).

The midpack is either firm, wind pressed surfaces or low density sugary snow in sheltered areas.

The Jan 7th layer is down 50-80cm, comprised of surface hoar and/or a thin crust on steep S aspects.

Weather Summary

Continuing cold as the arctic ridge persists.

Tonight Clear with cloudy periods. Alpine low -16°C. Ridge wind E 15km/hr.

Fri A mix of sun & cloud. Alpine high -14°C. Ridge wind: SW 10-20km/hr. Freezing Level at valley bottom.

Sat Cloud & sun with isolated flurries. Alpine high -15°C. Ridge wind W-20-30km/h.

Sun A mix of sun & cloud with flurries. Alpine high -18°C. Ridge wind NW 15-25km/h.

Terrain and Travel Advice

  • Make conservative terrain choices and avoid overhead hazard.
  • Be aware of the potential for remote triggering and large avalanches due to buried surface hoar.

Avalanche Problems

Persistent Slabs

20-40cms of recent snow is settling over a buried weak layer. This weak layer is consists of surface hoar, facets and suncrust (on south and west facing slopes). It will be most reactive where there is a settled cohesive slab.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 1 - 3

Wind Slabs

Variable winds have transported recent snow, creating wind affected snow on all aspects. Use caution in wind affected terrain and be aware that any wind slab avalanches could step down to our persistent weak layer

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 2
