From Avalanche Canada MIN reports: Dec 22, 2018

From South Coast Touring:
Mitchell Sulkers
Good day in the Hanging Lake zone yesterday. What a difference two weeks make.
At 1400m on a WSW aspect we found 400cm of snow. Numerous natural and sympathetic size one dry slabs running from steep convex features on various aspects in this zone.
Failure plane was a two cm thick facet layer over the 181219 crust/facet layer down 45cm from the surface. Storm slab 45cm fist density from most recent storm.
Compression and Extended Column tests failed easy to moderate (7-12 taps), Sudden Planar, on the facet layer.
We did not push up higher, anticipating larger windslabs up higher, but enjoyed very good tree skiing to 35 degrees. Ski pen from 20-50cm depending on elevation. 35cm new at valley bottom.
Base has suddenly exceeded last year's base at this time of season and even creeks are filling in well.
