Watch for changing conditions as you shift aspect and elevation.

    Expect to find deeper and more reactive deposits around ridgelines, these may remain triggerable by riders for several days.

    Loose snow can be found in sheltered areas, watch for storm snow gaining mass in steep features. Manage your sluff, and always have an exit plan.

Avalanche Summary

On Friday, explosive control and riders produced avalanches to size 1 within the storm snow.

Reports indicate the storm snow is beginning to settle and bond, however reactivity is expected to remain in specific features.

Snowpack Summary

Up to 90 cm of settling storm snow can be found overlying a widespread crust, or wind-affected surfaces at high alpine elevations. Another crust is buried around 20 cm below this. Reports suggest the snowpack is beginning to bond to these crusts, and gain strength.

The mid and lower snowpack are generally well consolidated. The recent snow has improved travel conditions at lower elevations, but many obstacles, such as sticks and rocks, lurk just below the surface.

Terrain and Travel Advice

  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Be especially cautious as you transition into wind affected terrain.
