Kananaskis.

Great weather forecast for getting up high and enjoying the views. The sun is starting to pack a punch, especially on the steeper south slopes.

Weather Forecast

Tomorrow looks like another beautiful day. Clear skies, daytime high of -7 and almost calm winds. There's no snow expected, but if it shapes up like today, the blue skies are a worthy trade. We did observe strong solar today. Despite it being January, expect the sun to pack some heat. 

Avalanche Summary

Nothing new today.

Snowpack Summary

Our snow pack condition varies greatly within the range. The northern portion looks wind hammered...more like clobbered actually. Hard windslabs, and even sastrugi are obvious in any open alpine area. As you move south it improves and looks better. Our trip today was around Mt Murray where the alpine windslabs were isolated and fairly well settled. The midpack generally feels solid, except for rocky thin areas-no surprise there. Below treeline is supportive with good travel. We did notice a very thin suncrust from today on steep treeline solar and new surface hoar up to about 2300m. 

Terrain and Travel

  • Avoid areas where the snow feels stiff and/or slabby.
  • Be alert to conditions that change with elevation and wind 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.
