Reminded me of the Huascaran avalanche (1970, killed approx 30K people) [0]. I'm surprised this is not also in the thousands of casualties (perhaps it'll get there) [0]
The main story in the wiki page comes from the Autopian [0], specifically from Jason Torchinsky, ex Jalopnik. It's an awesome publication, check them out, and Jason is an incredible writer (Onion alumni)
