Quick report

Sunshine, daydream, walking in the tall trees, going where the wind goes...

  • Traveled to the Northern Whitefish Range early this morning to nab an early corn harvest.
  • We found firm snow conditions on our ascent up to 6600' on aspects that are getting direct solar radiation this time of year.
  • Light to moderate winds have transported recent snow onto atypical aspects (SW-SE) along ridgelines and specific terrain features.
  • Decent coverage at mid-elevations made travel moderately pleasant while navigating through alder and dogwood.
isolated areas of recently formed wind slabs snow along ridgetops.

Partly cloudy skies in early morning transitioned to mostly sunny around noon. Cloud deck around 7000' along the continential divide in GNP. Winds light out of N-NE with moderate gusts along ridgelines.

Snowpack

  • Snow below 6600' has gone through a freeze/thaw cycle on aspects that are getting direct solar input.
  • Traveled up firm snowpack in the early AM, with softening conditions by early afternoon.
  • Recently formed wind slabs ranged from a few cm to up to 50 cm along ridgelines.
  • Small amount of wind loading across gullies, along ridgelines, and below convex terrain features.
