Quick report

Cracking
specific

We took advantage of generally stable conditions to enjoy a small slice of the terrain that the Middle Fork is known for. 

  • The snow surface remained frozen and supportable to boot-packing at all elevations through noon.
  • The upper-elevation surface was frozen upon our exit at 1415, with quality corn skiing found below roughly 5500 feet.
  • Thin slabs of wind-drifted snow were common at mid and upper elevations from recent southwest winds. These were harmless in the terrain we traveled.
  • No recent avalanche activity observed. Many south-facing paths have dirty debris piles confirming wet loose slides gouged down to the ground during one of the many warming events this spring. 
  • There remains plenty of snow at mid and upper elevations for spring riding. 
Thin, recently formed wind slabs rested on a thin layer of facets and dry snow atop a solid crust. This resulted in frequent cracking, with occasional shooting cracks. Slabs were only 2-4" thick, small, and generally harmless.

Mostly clear conditions, but cool air temperatures and wind kept the comfort level on the cool side.

Snowpack

We found the surface crust thick and stout at all elevations on the northerly slopes we traveled.
