Quick report

Cracking
isolated

Mike and I scheduled a welfare check for the Link Mountain weather station.  

  • We found surprisingly little wind effect throughout our tour, including exposed alpine terrain. 
  • I triggered a teeny-tiny slab below a small summit cornice.
  • Cold, dry snow sluffed easily on steep slopes and ran further than we expected. 
  • Our pit at 7100 feet on a North aspect revealed a deep and stable snowpack.
  • At 5500 to roughly 6500 feet there was 1+ feet of snow on top of the latest melt-freeze crust. 
  • Above 6500 feet we found over 3 feet of snow above the mid-December AR crust. 
  • We watched a group of sledders highmark steep, upper-elevation slopes without triggering sluff or slab. 

We felt comfortable skiing steep slopes one at a time and enjoyed great riding conditions. See you for your next de-riming Link!

Small but long-running sluffs on sustained steep slopes. Cracking confined to leeward (north) slope just below summit.
