Comments: 
There is a large crown fracture at the top 6' + deep, so it likely broke into older snowpack/slab. Looked like it happened on Sunday triggered by new snow. It could be as much as 2-3 hundred yards wide, and swept most of the upper basin in that aspect. I can't clearly see if it ran lower than around 9000'
Comments: 
The avalanche course just South-East of Little Baldy that I nicknamed "The Great White Worm" ran, likely on Sunday also. Multiple triggers, and multiple runs. There are a lot of leeward lips on the west side ridges. One lip at around 10,000' looks like an upper trigger. The runout continued to 6700' and stacked up high enough to match the height of surrounding Maples.
Comments: 
There are quite a few other lesser avalanches on the Southwest flank of Timpanogos. They all look like damp wet snow that bulled it's way through any obstacle.
