Comments
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 photo only shows about half of the fracture line which was about a half mile wide.
Comments
The debris pile was up to 20 feet deep in places.

Here is a close up of a portion of the crown where you can see that the avalanche broke near the ground.
