A video of man's terrifying six-minute encounter with a cougar on a hiking trail in Utah has gone viral.
Kyle Burgess was walking in Slate Canyon when he noticed the animal in front of him.
The video begins with Burgess taking a few steps in the cougar's direction before it scampers away.
But, it returns almost immediately and charges towards him, causing him to yell out as he runs away.
The animal continues to stalk him, periodically lunging towards him.
Burgess tries to scare it off with loud noises and after a few minutes he tosses a rock near the cougar's feet causing it to run off.
