While on a trip in the wilderness of Greenland, a hiker filmed a young musk ox that then sprinted at him in a terrifying mock charge.

The video shows the young bull ox spotting the hiker, before sprinting full tilt at him until it stops just short when he starts screaming at it.

The clip was taken during a 12 day trip into the Greenland wilderness in August 2015, with the filmer commenting: "When he saw me he quickly started attacking but fortunately stopped a couple of meters away from me.

"Good thing he did, otherwise I would have been left for almost 9 days without possibility of getting help, as there are no other people, no cell coverage and I had no satellite phone with me."
