Snowpack Summary

Previous alpine winds have made for variable surface conditions and formed small isolated pockets of thin windslab in the alpine. The Oct 25th crust can be found 30cm off the ground and likely encountered between 1800-2,700m. The snow cover below treeline is thin. Surface hoar has formed sporadically at valley bottoms last week up to 20mm.

Avalanche Summary

No patrol today and nothing new reported. Yesterday a few small surface loose avalanches noted in very steep alpine terrain. Remember to share the conditions found on your trip this weekend with Avalanche Canada's, Mountain Information Network
