    Feb 14th - now down 60-150 cm. This layer may have been the failure layer on the recent Pope's pk slide (MCR/facebook) & was remotely triggered in the Lake Louise slack country, yesterday. Winds will continue to load this layer, heads up in LL area.

    Strong SW winds will scrub some slopes tonight and load lee features. Avoid windloaded pockets/steeper slopes where a suncrust may be buried. We've found a range of easy to hard shears on this layer, pending on location.
