Quick report

Cracking
isolated

Today we went towards the crest of the Flathead to verify danger rating and assess recent wind drifting. For those curious about the approach, I'd give it a BW2.5 on the bushwack scale . If you'd like more information about the bushwack rating system, click here. This may come in handy this season. 

  • 6 to 12 inches of recent snow atop a pencil-hard melt-freeze crust from the Christmas warmup.
  • Winds channeled through terrain features and drifted snow onto varying aspects. Despite numerous efforts, we were not able to trigger any slabs of wind-drifted snow.
  • We actually found less drifting and better skiing above 7000 feet. Below 7000 feet was variable conditions with mostly windboard.
  • The Christmas crust stretched to 7700 feet. At this elevation, it was pencil to knife hard and 3 inches thick. The crust is slick. 
  • The upper snowpack is faceting. I observed 1-1.5mm facets above the Christmas crust.
  • We observed rollerballs and small point releases on south-facing slopes at middle elevations in the afternoon. Expect a sun crust moving forward.

Overall, conditions matched forecast. We felt comfortable stepping out into steeper terrain one at a time. 

Localized cracking around skis in wind drifted pockets. No shooting cracks and no triggered avalanches.

Unknown timing. This may have occurred during the warmup and rain on December 24/25. Tunnel recorded 41 degrees F and Noisy picked up .5 Precip during that time.
