Low density snow will be redistributed by moderate winds building fresh wind slabs in lee terrain features.
Shooting cracks are a good indicator of slab formation, test the snow as you go.
New snow and wind is building fresh wind slabs that may be touchy, especially where they have formed over a crust, facets or surface hoar.
In nearby Waterton, several size 1 to 1.5 dry loose and slab avalanches were reported on Sunday.
If you are getting out in the backcountry, please consider sharing your observations on the Mountain Information Network! You don't have to see an avalanche or dig in the snow to have useful observations - even weather and riding conditions are helpful, especially when you include photos!
15 cm of new snow coupled with strong winds is building wind slabs at upper elevations that are building over a variety of surfaces;
wind-pressed snow in high elevation lees
crust on exposed windward features, south aspects and low elevations
soft, faceted snow, possibly topped with small surface hoar crystals in sheltered areas.
The remainder of the snowpack is well consolidated, containing a number of crusts which are not of concern at this time.
