icefall

Northeast of the icefall, the glacier's surface is mostly smooth for several kilometers until a network of crevasses mark the surface.

It's the first flat spot you can reach after you get up to the top of the icefall.

Shifting ice exposes new crevasses with little warning, making the Khumbu Icefall the most dangerous section of a southern Everest ascent.

The treacherous Khumbu Icefall has taken the lives of many climbers on their first day as they head to their first camp.

The operation, called Operation Icefall, was led by officers from the Metropolitan police's clubs and vice unit.

A climber uses a ladder to cross a crevasse at Everest's Khumbu Icefall, not far above base camp.

Look at the walls and slopes of the Khumbu glacier [which flows 1. 5 miles down from an icefall on the southern flanks of Everest].

This is near the top of the icefall.
