Quick report

  • Our observations were largely focused on the effects of warming today. 
  • Surface snow was warming on solar aspects today near and below the treeline (2-5 cm around 11 am), with moist snow noted in areas with indirect sun and in more shaded aspects at lower elevations. In shaded areas above 8000'-8500', surface snow remained cold and dry.  This stark difference was obvious when transitioning from solar slopes to more shaded aspects or vise versa.
  • While ascending a solar aspect around 9500', it was easy to kick off some small rollerballs. And I noted several fans of roller balls in steep rocky areas in direct sun.
  • I triggered a small loose dry sluff on a steep north-facing slope at ~10,000'
  • All in all, it was a pretty good day in the hills.
Some roller balls were noted on solar aspects. Small loose dry sluff triggered on a steep north-facing slope around 10,000'
