Quick report

Cracking
isolated

We went to the eastern edge of the advisory area to check the snowpack..

  • At the trailhead, the 6 to 8 inches of recent snow barely covered the green bear grass.
  • True to the east sides reputation, the wind blew light to moderate throughout the day
  • Wind scoured and wind drifts were the predominant snow formation.
  • At 5400 feet, wind had formed 1-finger hard slabs that ranged from 55 to 80 cm in depth. These slabs were reactive in multiple tests. They all failed while cutting the back of an ECT with a snow saw. 

 

As we traveled through wind-drifted snow, we had isolated cracking around our skis.

Snowpack

  • Near the base of the snowpack, we found several inches of facets resting on a 2 inch ice crust.
