Snowpack Summary

By the morning of November 28th up to 15 cm could overlie variable snow surfaces, including small facets and/or surface hoar in sheltered areas and heavily wind-affected snow in exposed terrain.

A rain crust from early November is buried 40 to 90 cm deep and seems to be bonding well to overlying layers.

Alpine snow depths vary across the region, with up to 130 cm west of Smithers and around 60 cm to the east.

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Closely monitor how the new snow is bonding to the old surface.
