This is the widest avalanche that I have ever seen on the Skyline. This thing was massive. It released sometime between noon on Sunday, Feb 22 and 8am Tuesday, Feb 23. It should be noted that there was no new snowfall during the time it released. The trigger was solely wind drifted snow from a period of strong westerly wind.
The fracture line averaged 5 feet deep. There were sections that were easily 10 feet deep.
This avalanche measured 1.3 miles wide!!
It wrapped from southeast facing all the way through the northerly facing slopes to a far chute that has just a touch of a northwest aspect.
