Mount Everest is facing its deadliest climbing season in recent years, with at least 11 people reported dead so far in 2019.
Christopher John Kulish, a 62-year-old American citizen, was the latest casualty on Monday. He died after reaching the top of Everest on the Nepalese side of the mountain, a Nepalese official told Reuters.
While Everest has always been considered dangerous, this year has proven to be particularly devastating - with the recent slate of deaths attributed largely to overcrowding. The crowds have trapped climbers for hours in the mountain's deadly "death zone," where oxygen is limited and the body's cells begin to die. If climbers face too much time in that zone, they risk their lungs or brain filling with liquid.
British climber Robin Fisher died on Saturday while climbing Everest. In an Instagram post published just days before his death, Fisher wrote "around 700 more people will be looking to summit from Tuesday the 21st onwards... with a single route to the summit delays caused by overcrowding could prove fatal so I am hopeful my decision to go for the 25th will mean fewer people. Unless of course everyone else plays the same waiting game."
In total, when adding the 11 people who've reportedly died in 2019 there have been 306 recorded fatalities on the mountain.
