[MCR] Recent Large Avalanches in the Rockies

Approximately 50 cm of recent storm snow
has fallen in the last few days, which has resulted in several large and
destructive avalanches in the Lake Louise area.  These have initiated
on the storm snow, Valentines surface hoar and basal facet interfaces depending
on their location.  Of particular note are two events that occurred
in the last 24h (see pictures):

• NE aspect of Cathedral peak which most likely involved the storm snow interface.
• N aspect in skiiable terrain on the Popes peak tour and likely stepped down to the Valentines surface hoar.  

In addition, there was another close
call with an avalanche that failed on the basal facets in West Bowl in
the Lake Louise Backcountry yesterday afternoon, and Parks Canada was called
out to search the debris.

It seems all of this recent snow is
awakening some older weak layers that have been lying dormant for a while.
