Quick report

It felt like spring skiing in the Swan today, with mild temps, no winds, and sunshine.

  • The snow was moist up to approximately 7000 feet, even on northerlies.
  • Evidence of a recent upper-elevation thermal belt in the form of a thin surface crust was noted in northern aspects. 
  • Recent snow above the 12/22 crust is consolidating with ambient above-freezing air temperatures.
  • Evidence of trees shedding snow was a good indicator that the sun had been warming above 6000 feet.
  • In the terrain we traveled, we did not observe wind-drifted snow.
  • Below 6000 feet, we snowmobiled on very thin coverage. Yikes! 
No avalanches or instability observed.

Snowpack

Our snowpit at 7100 feet on a north aspect was 95 cm deep. The 12/7 crust was down 40 cm and 3" thick. We had no propagation in large-column tests.
