Quick report

Sunshine or powder? We had some of each:

  • Increasing cloud cover and light southerly winds shut down today's expected warming, 
  • We saw only a handful of rollerballs and no wet loose during our travel 
  • We saw many signs of recent southwest winds
  • We observed minimal blowing snow and no cracking.
  • We found the 1/31 facet layer buried 4+ feet deep and under a series of crusts from early March. 
  • These facets are rounding out but still produced unstable results in pit tests.

We skied planar, wind sheltered terrain and traveled one at a time on the steepest sections. 

No obvious signs of instability.

Noted 1 crown from February AR and 1 debris pile from warming 3/1-3/2. Also one debris pile from wind-loaded slope that looked to have occured during the last 1-2 weeks.
