Quick report
Windshield tour welfare check on the Flathead Range and southern GNP.
- On shaded slopes, snowline appears to be at about 6000 feet - lower in debris-filled avalanche paths and steep, leeward bowls near the crest of the range.
- Sunny slopes generally have patchy snow cover or are bare, except on slopes where drifted snow augments the seasonal snowpack, and/ or on slopes near the Divide or Flathead crest.
- Many snow-coered slopes are peppered with rocks, indicating that the snow cover is thinning.
- One very large natural avalanche ran in the past few days, possibly triggered by cornice fall. It released on old snow, possibly the January Drought Layer. See avalanche obs.
- A few crowns from large natural avalanches were also visible, though they appeared much older.
- Isolated wet loose snow avalanche activity apparent.
