Regions

Kananaskis.

Winter has arrived this past week and climbers and skiers need to be thinking about avalanche conditions.  Share you observsations on the MIN as this time of year we are fairly data sparse....

Weather Forecast

Snow will continue early this week before returning to more seasonal fall temperatures.

Avalanche Summary

Observations are limited but there has been evidence of loose dry avalanches from steeper terrain up to sz 2. Get on the MIN, Email us, facebook us etc. Share what you are seeing! [email protected]

Snowpack Summary

Up to 40-50cm of snow can be found at treeline in some areas with areas or windblown snow up to 1m. Lots of early season hazards exist and observations are limited but winter has seemed to arrive here this past week. If there is enough snow to ride, there is enough to slide. Where people are commonly keen to go is where its blown in ie. Windslabs. Be thinking about consequences if you choose to ski. Ice climbers be aware that loose dry sluffs can have large consequences on routes. Pockets of windslabs may also be found along routes in benched terrain or along ridgelines/side walls of gullies.

Problems

Loose Dry

Loose Dry avalanches are the release of dry unconsolidated snow and typically occur within layers of soft snow near the surface of the snowpack. These avalanches start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-dry avalanches include point-release avalanches or sluffs.

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.
