As the world’s tallest peak, Mount Everest draws more than 500 climbers each spring to attempt the summit during a small window of favorable conditions on the rugged Himalayan mountain that tops out at just over 29,000 feet.

A new study led by researchers at the University of Washington and the University of California, Davis, finds that the success rate of summiting Mount Everest has doubled in the last three decades, even though the number of climbers has greatly increased, crowding the narrow route through the dangerous “death zone” near the summit. However, the death rate for climbers has hovered unchanged at around 1% since 1990.

The findings were published Aug. 26 in the open-access journal PLOS ONE. They represent the most comprehensive look at success and death rates in the published literature on Everest. The paper also identifies patterns in the characteristics of mountaineers — such as age, sex and prior experience — that might influence their likelihood of summiting or dying during the spring climbing season.
