The Khumbu Icefall is a graveyard of shattered glaciers. This week, a massive ice block the size of a double-decker bus collapsed across the Hillary Step, trapping 47 climbers above 8,000 metres. British mountaineers, using techniques honed on the Eiger, carved a bypass through the debris in 14 hours.
The rescue succeeded not through heroics but through physics: the block was unstable, its internal temperature just 2 degrees Celsius below melting point. This is the new reality of high-altitude climbing. The Khumbu Glacier has retreated 1.
6 kilometres since 1960. Each summer, the icefall grows more unpredictable. Seasoned Sherpas now carry portable weather stations; the old maps are discarded.
The team used ground-penetrating radar to find solid ground. The lesson is clear: the mountain is changing, and our methods must change with it. The climbers are descending, but the ice is not finished with us.
Calm urgency is the only sane response.
