Got out in a helicopter this morning in the Mountain Loop area. I saw a number of natural slab avalanches, some of which looked relatively new (no snow on top) while some were larger older ones. The one on the west side of Three Fingers is a large old one which I suspect failed on the mid January persistent weak layer. I also saw some glide cracks and glide avalanches. Most avalanches were seen (or at least started) in the ATL zone.
