Snowpack Summary

40-60 cm of snow is on the ground in the area surrounding Cameron Lake. 10-20cm of recent storm snow has formed new windslabs in the alpine and at tree line with recent strong to extreme west winds. The October/November crust complex is present below 1950m on all aspects, and the lower snowpack is weak and facetted. Lower hazard on eastern slope

Avalanche Summary

Forecasters observed two windslabs to size 1.5 on a field trip up the Akamina Parkway, but poor visibility has limited our observations.

Confidence

Due to the number of field observations
