Observer Comments

Large (D2) persistent slab avalanche in Rae Wallace Chutes triggered by cornice fall sometime overnight Monday March 25. See separate observation for more details. Natural wet loose avalanches off the southwest side of Gold Chord Peak that have occurred sometime since Sunday. One looked like it may be large enough to bury, injure, or kill a person but difficult to tell from our vantage point.
