With temperatures warming slightly, human triggers may continue to cause failures in isolated pockets of wind slab.

Seek out sheltered terrain to find the best conditions for skiing and riding.

A few size one dry loose avalanches out of steep terrain along the Icefields Parkway were reported on Thursday.

10-20cm of soft snow can be found in sheltered locations sitting on various melt freeze crusts and older wind affected snow, or a patchy surface hoar layer below treeline. The midpack is generally dense and well consolidated with basal facets in thin snowpack areas.
