The 2 northerly of the 3 Avy paths at the end of the east ridge of Apex Proper. The debris ran across the road that forms the Orange trail in that location. Strong NW winds in the previous 5 days which tends to load these slopes. The middle Avy path (first 5 pics) last slid in early January 2020. The larger northerly path had yet to slide this season.
