Myself and Lisa Paulson skiied from Bow to Sherbrooke on Feb. 4-6th.  We circumnavigated Gordon via the West slopes, attempted to summit Balfour, and then skiied out via the benches below Mt. Niles.  Here are a few observations:
  • We found good travel conditions with variable snow depths on the glaciers ranging from 25cm on scoured areas above bow hut to 3m +.  
  • Ski pen was 5-10cm which made for good gliding on the low angled terrain.
  • Mild alpine temperatures with light winds and clear weather dominated.
  • The Balfour high col was in good shape.  We took the high bench, but the crevasse on the normal route looked well filled in (see picture)
  • The only recent  natural avalanche activity we saw was wet loose snow avalanches from steep, rocky south aspects in the late afternoon sun.

We had a close call on the summit slope of Mt. Balfour on Sunday, Feb. 5th.  We remote triggered a size 2 avalanche on a steep south aspect at 3000m elevation.  The avalanche was a windslab on facets, and took one of us for a short ride (see picture).  Luckily, no one was injured.  This incident shows that there may still be some lingering instabilities in the high alpine that may take a little longer to heal.  After all, it's still early February in a Rockies snowpack that has seen a lot of wind this season.  

Stay safe out there.
