Quick report

Went to check on the access and snowpack in the Swan Lake area:

  • Total snow depth was 1 foot or less up to 6000'
  • Above 6000' the snowpack doubled to 2 feet
  • We found the 12/7 crust burried 10-16 inches deep up to 6800' (our high point)
  • Dry powder snow was in limited supply on our southerly route
  • Current snow surfaces featured: a thin melt freeze crust, wet snow, and surface hoar (which was getting nuked in the sun)
  • We briefly dipped onto a North aspect at 6800' and found buried surface hoar which yeilded an unstable result in a large column test.

The descent was rough.
