Main concern is for cross loaded gully features and steep rocky convexities on lee aspects where fresh windslabs are present.
The weak lower snowpack is susceptible to triggering in lee areas that have been recently loaded by SW winds and last week's snow.
Deep persistent slabs are best managed by:
Cornices are best managed by:
No new precipitation on the horizon. Slight cooling and cooling trend towards mid-week, with calm to light Southerly winds.
Recent 20-30cm of rapidly settling and wind distributed storm snow overlies facets and basal weakness. New reactive windslabs in lee gully features and especially on NE aspects. Extensive scouring of last weeks snowfall at and above treeline.
Good results (several size 2 to 2.5 in steep rocky alpine terrain) in recent explosive control work at Marmot ski hill, suggests that the weak basal layer is reactive to large loads. No patrol in the Columbia Icefield area today.
