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

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

Weather Forecast

Similar mild temperatures and very little snow are in the forecast.

Snowpack Summary

Variable snow distribution in the alpine ranging from 0 - 220cm. At treeline , there is consistent coverage around 60cm.  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

Freezing levels are uncertain
