A party of 2 skied off of pink pine ridge. We noticed lots of sluffs and some fracturing on the main slope when we skid it and commented that we would not want to ski anything steeper than what we were on. While skiing the bottom of the drainage the first skier triggered an avalanche in the new snow that broke above both skiers. The first skier was able ski to a safe area while the second was knocked of their feet. While pulling their ski from beneath the debris the second skier observed that the avalanche had started about 100' above them on a roll over in some trees and was about 6-8" of the new snow that slid.
