Avalanche Summary

A few small loose dry avalanches were observed in the Alpine on Saturday.

Snowpack Summary

Check here for how to navigate Early Season Conditions

Our field team ventured out to Hilda Ridge on Saturday and found generally supportive travel. Early season hazards exist with snow just covering rocks & trees.

Treeline has 30-55cm. The alpine is highly variable with either scoured back to rocks or loaded areas of over 100cm. Where the snow does exist there are windslabs. Alpine bowls & steep gullies are classic spots for early season avalanches.

Terrain and Travel Advice

Be careful as you transition into wind-affected terrain.

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.
