Avalanche Summary
No avalanche activity reported, but, I suspect there was a fair amount of activity Monday as the snowpack adjusted to it's new load.
Snowpack Summary
Saturday night into Sunday, moisture in the west of the region collided with cold air in the east and resulted in an intense period of heavy snowfall that was very low density. This new snow has likely settled a bit with daytime warming Monday. Now 50-60 cm of recent snow sits on a highly reactive weak layer of crusts, surface hoar and facets. At 1950 metres elevation we have some snow pack test results from Friday that show that the 40 cm slab of snow above the February 8th weak layer is sliding with easy to moderate forces applied and it is propagating widely with either sudden planar or sudden collapse characteristics. The slab is reported to be less consolidated on northerly aspects than it is on southerly aspects. In areas further north, less snow has fallen on this interface--in the northern Elk Valley for instance, only around 15-20 cm lies above this interface. In lower snow areas, avalanche activity will likely lag behind higher snow areas, except for areas which have seen significant wind transport. In general, the mid-pack is quite strong in most locations. However, lingering concern remains for basal facets, particularly in shallower snowpack areas with steep, rocky start zones.
