This is really a strange case. Avalanche seems at least plausible, but doesn’t explain the injuries. Would be interesting to know more about the injuries (e.g. level of confidence that they were not post-mortem). First rumblings, snow covers the tent so they have to cut out. Hear more rumblings and take off with whatever they have on to get to shelter. Then realize they are going to freeze, so they try to go back to the tent. Injuries due to initial events/ predation?
Excellent explanation. I hadn’t read the entire article. It’s certainly plausible. That or the Blair witch, eh?
