Observer Comments

Large whumpf around 3000' while climbing the common bowl ridge, surprising us. 3 of us were all grouped fairly close together when it occured. Multiple loose slides. Roller balls off of the cornices on CFR and Hippie bowl. Fairly large debris pile down a chute between Todd's run and the common bowl.
