Hi Maybe the earthquakes are working the rock loose on the face , we could feel the shaking in the Portal and others said they could feel motion in the Iceberg lake area. A rock fall on the buttress route, hit a climber yesterday and he was flown out this AM , the size of rock that hit the climber is not normal for the area and time of year , he was wearing a helment and should be ok. His climbing partner did a very fine job of lowering him down into the chute and getting him to Iceberg for the air lift this AM.Thanks Doug
