Points saillants

By Tues, accumulations of up to 20cm can be expected in the alpine. Currently this is not enough to alter the danger ratings. Today a skier remote size 2 was reported on the Crowfoot Glacier on a N aspect. There is still potential out there.

    The Valentines surface hoar is 70-150cm down. Avalanche control was still producing the odd slide on this layer today. Typically from steep terrain with a shallow snowpack.

    Although difficult to initiate, it is still possible to trigger a deep persistent slab. Heavy loads in steep terrain with shallow snow are the most likely areas to produce an avalanche on this layer.
