Avalanche Summary

Several MINs from the Coquihalla area on Friday and Saturday reported wind-affected snow, shooting cracks and a few small skier-triggered wind slabs.

Thank you for all the great MINs! We love it when you share your observations and photos on the Mountain Information Network (MIN)!

Snowpack Summary

Recent snow has seen moderate redistribution in wind-exposed terrain. Good snow quality has been reported in wind-sheltered areas.

A substantial crust up to 30 cm thick sits 50 to 100 cm deep, well-bonded to surrounding snow. The mid and lower snowpack is generally well consolidated, with several well-bonded crusts scattered throughout.

Treeline snow depths range from roughly 150 to 220 cm around the Coquihalla and 100 to 150 cm around Manning Park.
