When Edmund Hillary and Tenzing Norgay reached the summit of Mount Everest 60 years ago Wednesday, the mountaineers gazed over a view from the top of the world that had never been seen before.
The view has changed since that historic day. Pollution and rising mountain temperatures are relentlessly shearing away at the Himalayas’ frozen façade. Photographs taken around the time of the 1953 expedition show hulking ridges of ice that have since shrunk or disappeared.
Glaciers and snow are melting throughout the sprawling mountain range, which stretches across India, Pakistan, Afghanistan, Bhutan, Nepal, and Tibetan China. The waning glaciers are leaving precarious mountainside lakes of cyan blue water in their wake.
