As of 2014, over 200 of the climbers who have attempted to scale Mount Everest, the highest mountain in the world at approximately 29,029 feet (8,848 m,) have not survived. These fallen hikers’ bodies are used as landmarks on Everest for other climbers. The corpses are typically left on the mountain because it would be too dangerous to attempt to move them down off the mountain. Due to the freezing temperatures, many of the bodies of the fallen hikers are well-preserved in the ice and snow. Climbers have died of falls, freezing temperatures, avalanches, exhaustion, and altitude sickness.
