A climber made a nail-biting 2,019m ascent on a limestone ridge - no wider than his shoulders.
Alpinist Dani Arnold, 39, braved the razor-thin ridge with sheer long drops on each side.
An amazing video shows the climber scrambling up the "rare" rock formation on Kreuzberg mountain in eastern Switzerland.
Dani encountered the formation two hours into a six-hour climb., which he carried out with fellow climber, Michi, 55.
Dani, a true professional, loved climbing the uniquely shaped mountain as it was quite different from his other climbs.
He said: "What's very unique is the big size of this piece of rock. It was amazing to climb it.
"I enjoyed it very well. You're so exposed when you're up there. Every rock is unique but it's nothing very very special.
"I would say that it's fairly rare."
Dani chose this particular route because he simply had never done it before.
He added: "The climb took me one day including the approach. I chose it because I had never done it before."
The alpinist is a world-renowned climber and mountaineer, and has broken several speed-climbing records.
He has broken multiple separate climbing and alpinism records and still holds a worldwide speed-climbing record.
In 2015, he did the fastest solo ascent of the North Face of the legendary Matterhorn, by finishing in just under two hours.
He holds two of the three records of the Matterhorn's North Face to this day and has broken multiple others around Europe.
