Death Zone, Mt. Everest, Nepal
This is a pretty depressing name for the highest altitudes of Mt. Everest. Anything above 8,000 metres (of the total 8,848m height), is where the oxygen becomes so thin that you can’t breathe without oxygen. At this point, between the lack of oxygen, exhaustion, extreme cold and various climbing hazards, mean that the majority of the 200+ lives that Mt. Everest has claimed, have been here.
Since rescuing or carrying an injured climate back to basecamp is impractical, they’re typically left there to die. So far, about 150 corpses are unrecovered and it’s not crazy to find corpses alongside the standard climbing routes, frozen in their last moments, trying to make it back down.
