I spent the last 4 days (Feb 6-9) with a group of Park Wardens in Flat Creek, on the west side of Glacier National Park, about 8 km south of the highway.
We enjoyed excellent snow quality and mild temperatures. Approximately 20 cm of new snow fell over the four day period.
The February 4th surface hoar layer is now buried about 30 cm, and has become reactive to skier triggering. Watch for this layer, especially if you are in the Monashees or Selkirks. With a forecast for additional snow load and wind over the next few days, this layer is likely to become more reactive, and with bigger consequences. Use extra caution in steep open areas at treeline and below. Avoid terrain traps like gullies or creek draws that can significantly increase burial depths if you are caught in a slide. If you are caught in an avalanche in a glade and are pushed into the trees below, or over a rock bluff, there is a high probability of trauma in addition to being buried.
There have been numerous recent observations of cracking, whumphing, and skier controlled avalanches. This is a sign of instability. Use extra caution if you do venture onto the slopes in the next few days. With the avalanche danger in the Selkirks and Monashees sitting at ‘Considerable’, this is a prime time for avalanche accidents.
