If you are going out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).
Snowpack Summary
New snowfall is expected to begin to bury surface hoar that may still exist in wind-sheltered, open terrain. A thin melt-freeze crust on south-facing slopes in the alpine is likely to become buried down a enstimated 10 to 15 cm.
In the alpine, an estimated 30 to 50 cm of old snow sits above a thin crust. At lower elevations, 10 to 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 95 cm is reported in the Coquihalla and 65 cm near Manning Park.
