In the alpine, 20 to 40 cm of snow from last weekend sits above a thin crust. At lower elevations, 10-20 cm of snow sits above a more robust crust. The snow is moist below the crust.
Snow depths at treeline vary across the region. Around 90 cm is reported in the Coquihalla and 60 cm near Manning Park.
