Avalanche: Summit
Location: Summit Ridge
Toured up through the trees and alders along the summertime FS trail. As we cleared alder line at 11:00a, we saw a small/moderate sized wet loose avalanche come off the rocks above us. We had expected to have another couple hours before seeing that kind of activity. After a lot of discussion, we decided we should have got an earlier start on the day and bailed out. When we got back to the truck we saw that there were many new wet loose avalanches along the entire southeast face of Summit. All looked to be R1-D1, might have been one that was D1.5. We were surprised to see all of this happen before noon, but looking back we should have expected the combination of barely below freezing overnight temps, clear sky, and easterly aspect to bump up the timeline of solar effects.
