Opinion: What’s behind the logjam in Mount Everest’s ‘death zone’

The photo says it all: A queue of what looks like more than 100 bundled-up climbers lining the top ridge of Mount Everest like a human mohawk, each waiting their turn to get to the summit. It’s an area known as the “death zone,” since there isn’t enough oxygen in the atmosphere to breathe unaided for more than a few minutes. Climbers bring extra supplies, but the long lines have, many say, contributed to a record 11 deaths this year on Everest.
