Avalanche Summary

Avalanche control was done on Wednesday on the Canmore Hill and the upper bowls produce a few size 2 slabs (wind slabs). 

Snowpack Summary

The forecasters did avalanche control on Wednesday and noticed a lot of wind effect in the alpine. Currently 50-70cm of snow is at treeline with a temperature crust related to recent rains 10-20cm off the ground. We don't have a firm grasp on how high this crust goes at this time due to limited field observations.  

Terrain and Travel

  • Be alert to conditions that change with elevation, aspect and exposure to wind.
  • Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.
