January 29, 2017


    When some of the old rules are broken.  Story below.                                           Nancy Zenger Pic
Size 1.5 skier triggered avalanche today by co-pilot. The skier triggered it after traversing above the skier on the uptrack - the crown was way above at the top of the slope and it was about 5-8cms of wind slab. Skier carried down to where she is pictured in front of me - she worked to stay on top of the snow and was unharmed. The snow was really variable today and changed quickly ever few meters. Be careful out there folks!

    Old wet avalanches near the valley bottom.

    Locally Na and Sr Sz 1-1.5 ssl , strong SSW winds yesterday.


 Blackcomb from a distance.

   Surface Hoar Face.

    Nice snow in the backcountry.

    Later in the day, clouds from the approaching Cold Front.

    Saturday Morning.

  As of 07:00 Hrs this am we have overcast skies with unlimited visibility.


A weakening cold front will bring overcast skies with light snow fall beginning this am for most of the day in a Southwesterly flow aloft. The FL could go as high as 1800 meters today then slowly move back to surface by tomorrow am with the passage of the cold front.  Monday is also looking overcast with left over moisture from the frontal band, in a Westerly flow aloft.  Drier and cold continental air will infiltrate the zone for Tuesday with an upper level trough moving through the zone in a Northerly flow aloft. Modified arctic air will bring another session of cold temperatures to the area this week.  Unfortunately the rex block looks like it will bring a dry cold weather pattern for Wednesday through Friday. As of now there will be no change until Friday night, when we hopefully return to a moist Southwest flow.. Guesstimates: 8-12 cm by Monday morning, trace-2 cm by Tuesday morning.

   Weakening cold front pushes through today with lingering moisture for Monday.

   Flow for today.

    Front will likely bring snow to the area this afternoon.

   Lingering cloud for Monday.

Size 2.5/3 avalanche today while skiing the North couloir on Thar in the Coquihalla. We rappelled the upper exposed sections then skied down. Two skiers were caught. One was able to stop himself after 20-30 feet of sliding. The other pulled his airbag and slid all the way until the point where this picture was taken. Both skiers remained on the surface and are okay. The crown line was 2.5 feet deep and spanned the entire couloir. A surprise wind slab was to blame, sitting on the old wind effected layer from a week and a half ago. Before this point the snow showed no concerns. All three of us were very lucky to escape unharmed.

Had a great little day showing some friends the musical bumps. Ended up digging a little pit at 1930m on Oboes NWW face. Recorded 2 CTE5 SC releases down 65cm to a huge faceted layer. These low/moderate avalanche ratings can be deceiving. Was a little surprised with how easy this released. Be careful everyone.

     Skied Cayoosh area today.                                                                                             Bridget Mcclarty Image

Saw this avalanche on the uptrack on Armchair Glacier, just above TL, past the moraine. Likely slid within the last 24 hrs. Bridget

   Good size surface hoar, new snow will be burying it.

   Loose moist point releases from Friday.

    Evidence of natural wind slabs.

    Wind transport in the alpine most of the day Saturday, especially south of Whistler..
