Hillary and Norgay.
Jamling Tenzing NorgayHillary and Norgay.

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 facade. 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.

So much of the ice has disappeared that climbers following in Hillary and Norgay’s footsteps this spring climbing season, including two octogenarians, are encountering rockier cliff faces that are less stable than the ice that was scaled by the mountain’s first conquerors.

“There is a big change compared to when I first climbed,” says Apa Sherpa, 53, a retired Nepalese mountain guide who scaled Mount Everest a record-setting 21 times from 1990 until 2011. He has lived in Utah since 2006 but still visits Nepal every spring or fall, where he participates in treks and climate campaigns.
