The Manti Skyline went through a natural avalanche cycle during the last storm and following warm up. Many natural avalanches occurred during the storm on Thursday, March 1. Many also released during the significant warm up on Sunday, March 4. It appears that all of them involved the weak facets from early in the season as well as a layer that formed in early February.
This avalanche most likely ran during the storm.
This was actually two avalanches that ran sympathetic to each other with the largest portion almost a half mile wide on an east southeast aspect seen here.
The other portion was on a northeast facing aspect and almost a quarter mile wide just adjacent to the larger portion.
This was the largest and most destructive avalanche that we viewed.
