Skied at June Mountain yesterday, February 26th. Here are a few observations that confirm the avalanche danger rating from yesterday and give us some more information moving forward into the next round of storms and winds moving into our area today.

  • Strong winds from the W – SW yesterday transported huge amounts of snow and loaded slopes from ridge-top elevations all the way down to mid-slope and below on all the high peaks visible from June Mountain.
  • Skiing inbounds at June Mountain I triggered several small but reactive wind slabs, cornice breaks and long shooting cracks. Evidence to the wind-loading that continued to occur post control throughout the day.
  • A large slide and debris that ran almost full path could be seen in Dream Bowl. This probably ran during the last storm.
