Everest Expeditions in numbers


What influences the success or failure of an expedition to the highest mountain on Earth?

Introduction

A journey to Mount Everest comes with various challenges. This website showcases various visualizations of data of expeditions from the early 1900s up until 2019, and explores the effect different factors, such as the use of oxygen, on the success of reaching the summit. We hope our project provides aspiring climbers, mountaineering historians and everyone else with useful information on our highest mountain.
