In sintesi

15cm of new snow at Parkers Ridge has improved the ski quality on the Icefields Parkway. Keep in mind that our low snowpack means rocks, stumps, and other hazards may be hidden just below the surface.

    You must keep this basal layer on your radar as triggering is possible in isolated features, such as steep rocky terrain where you find yourself standing on the surface and not wallowing in facets, that's the problem slab.
