    This layer was easy to identify 10cm down from the surface. On lee aspects this may sweep a person off their feet.

    This layer showed in tests around the Columbia Icefields area from 2200m to 2400m. It released with a sudden planar character between two dense layers which indicates that it could be a buried surface hoar layer.

Weather Forecast

Light snowfalls are expected overnight, with slightly more snow in the Icefields. A second front will follow with increasing amounts of snow expected to arrive on Monday and Tuesday.

Snowpack Summary

Variable snow distribution in the alpine ranging from 0 - 220cm. There is consistent coverage around 60cm at treeline.? Two midpack crusts are providing good support. Below treeline, snow depths are? below critical levels to cause an avalanche.

Avalanche Summary

No new avalanches have been observed in the last week. Several slab avalanches to size 2.5 occurred approximately 10 days ago, on a glaciated NE lee aspect in the high alpine.

Confidence

Timing, track, or intensity of incoming weather system is uncertain on Monday
