Two American men and a Canadian man are missing after they failed to return from their attempt to summit New Zealand’s tallest peak on Monday.

Mountaineers were doing some ice climbing while waiting for their K2 summit push, when all of the sudden, an avalanche starts. Watch it here.

A mountain guide captured a mountaineer climbing the Matterhorn without proper equipment. A climber fell that day. Was it the same man?

Rescuers recovered the bodies of two Austrian mountaineers. They were 2,000 meters up, dangling from their ropes.
