> I noticed this crown on the north facing slope of North Leigh Creek. Looking at my map, my best guess is it’s at an elevation of 8,200 ft. As i studied the image it became a bit alarming to me that the fracture propagated across a laterally convex slope (think like a broad ridge, fracturing from one side to the other). Is this what you see? Click on the image for the large version.
It appears this particular slope gets wind loaded from the ridge line above the band of trees. This is a great reminder how far wind transported snow can go; effectively wind loading slopes quite a ways down hill from the source.
