Kilian Jornet had a close call while attempting the West Ridge route made famous by Willie Unsoeld and Tom Hornbein.
Hornbein and Unsoeld’s West Ridge route starts by gaining the ridge from a couloir slightly above Camp 2 on Everest’s normal route. It was not an easy first stage for Jornet. He describes the conditions as “horrible, with blue ice underneath and a top layer of deep snow. [it meant taking] two steps up and one down for 1,000m.”

Swept down by avalanche
Once on the ridge, he waited three hours for the winds to drop, sheltered by a cornice. He then proceeded over mixed terrain to the base of the Hornbein Couloir. He climbed this for “a few hundred meters.”
Then he broke a wind slab and triggered an avalanche that swept him down some 50 meters. After some consideration, he decided to turn around at that point. He descended in a heavy snowfall, with his previous footprints totally buried, and two to three meters of visibility. It was “interesting,” the athlete admitted.

In the end, Jornet made it safely back to Base Camp, without a summit but not necessarily unhappy.
“I’m a big believer in the how is way bigger and more important than the what,” he concluded. “In that sense, the climb was just perfect.”
Here’s a brief video he took during the climb:
