    Pockets of hard deep slabs in gullied terrain and in alpine terrain. Ice climbers should pay attention to drummy feel as the move across isolated snow coverred slopes and gullies.

Terrain and Travel Advice

  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
  • Small avalanches may cause climbers to fall or belayers and gear to become buried.
  • Ice climbers should be equipped with avalanche safety gear.

Avalanche Summary

No new avalanches were observed or reported on Friday.

Snowpack Summary

The front ranges within the Kananaskis valley are very dry for this time of year. The main concern is pockets of hard slabs in alpine terrain that if triggerred will likely fail to ground. Lots of bare rock is exposed and thin weak areas surrounding the lens of hard slabs should be avoided.
