Regions

Glacier.

Watch out for pockets of windslab in open terrain.

Make ongoing snowpack assessments as you move into new terrain.

Confidence

Moderate

Avalanche Summary

We experienced a widespread natural avalanche cycle in the Park last weekend. Lots of evidence of this cycle is still easy to see.

The Min reports of large avalanches in the Connaught drainages are worth a read.

Natural activity has slowed down but human triggering remains possible.

Snowpack Summary

Winds have created wind effect in the Alpine and exposed tree line areas. 40- 60 cm of new storm snow fell over the weekend. This storm snow sits on a crust that exists up to approximately 2200m.

Recent sun has created a thin sun crust on solar slopes.

Early season hazards exist below treeline with a low early season snowpack.

Terrain and Travel Advice

  • Make observations and continually assess conditions as you travel.

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.
