A rock climber has described how he miraculously survived a terrifying 400ft plunge that killed his three friends.

Anton Tselykh, 38, had been climbing in Washington's North Cascades mountains when the anchor his group were tethered to gave way, sending them all plummeting down the rock face.

Speaking from a hospital bed in Seattle, Tselykh recounted how the men fell for about 200ft into a slanted gulch and then tumbled another 200ft before coming to a stop.

He described losing consciousness for several hours before waking up in the dark surrounded by a tangle of ropes and gear.

Despite sustaining serious injuries, he fought for eight hours to free himself before working his way down the rough terrain of rock and snow to his car.
