Notes

From facebook on 2/16/24: "Rode up Portal creek today ... We triggered 4 avalanches with the farthest one being 300 yards away. The one in the photo was the scariest one. We were playing below the windy pass hillclimb and the chute next to it let go. We had a sledder almost get caught in it, but thankfully everyone was ok. It's scary out there!"
