Regions

Kananaskis, Bow Valley, Highwood Pass, North 40, Spray - KLakes.

A small refresh of snow has spruced up the skiing. The sun came out and SE-W aspects had moist surface snow upto 2200m by end of day. Polar aspects still holding cold snow

Confidence

Avalanche Summary

Small loose dry out of extreme terrain. No new slabs observed.

Old avalanche debris now has roughly 40cm of snow on top, Still tough skiing over this debris

Snowpack Summary

March 24th crust is down 40-50cm up to 2450m with facets starting to develop on the interface. Snow pluming off the peaks all day, but no wind effect noted in skied area's. Solar aspects below 2200m were becoming moist first thing in the morning, but a cold wind kept the higher elevations cold.

Weather Summary

Tuesday: Cloudy with sunny periods

No new snow in forecast and a daytime high of -7

Light winds out of the Southwest.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

Carefully evaluate steep lines for wind slabs.
Be careful as you transition into wind-affected terrain.
Be alert to conditions that change with elevation and sun exposure.

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.

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
