Quick report

Cracking
specific

I slogged through trap-door snow and poor visibility to get a baseline sense of the snowpack and look at storm instabilities in the Bishop Creek drainage. 

  • I got long, shooting cracks breaking in lower-density snow under a cohesive slab at the surface.
  • I did not find any persistent grains in my snow pits. The snowpack is upside-down and still thin, especially below 9000 ft. 
  • Snowfall rates and blowing snow increased throughout the day.
Shooting cracks were breaking under a more cohesive (temp-thickened or wind-deposited) slab 15-45 cm thick on top of less dense snow from last night.

Increasing snowfall and wind throughout the day. Temps hovered around freezing and began to fall in the afternoon.

Snowpack

The snowpack still has sage and rocks poking through below about 9000 ft. Snow depth ranged from 20-50 cm. Around 9400 ft: windward aspects had less than 80 cm, while leeward aspects had 100-135 cm. I did not find persistent weak layers anywhere. My snowpack test propagated at the same interface that I got shooting cracks - under a cohesive wind slab in the softer recent snow.
