Perhaps the most dangerous animal lurking in Colorado's vast wilderness, mountain lion encounters are no joke.

The terrifying footage below was captured by Kyle Burgess during a run in Slate Canyon, which is found near Provo, Utah. It shows how scary a mountain lion encounter can be, especially when the lion starts lunging toward Burgess around 2 minutes and 45 seconds into the encounter.

WARNING: This video contains a lot of profanity. Rightfully so.

It's likely the lion in this video was so aggressive because kits were around, as seen when a small lion turns to run at the beginning of the video. Mountain lions are more likely to be more brazen when defending their children. As one reader pointed out, the mountain lion was likely pursuing Burgess as a means of driving him away from the kits.

Burgess did a lot of right things during this encounter that should be mentioned.

1. He didn't run, he slowly backed away. This can help prevent a charge response from the lion.

2. He maintained eye contact with the lion as much as possible. Something to note is that the lion seems to charge when he turns back to spot the trail showing how important this eye contact is to keep the lion at a distance.

3. He made loud noises to try to scare off the cat. This is one thing he probably could have done more, though the cat seemed undeterred by his yelling.

4. He tried to make himself big. Though this isn't seen in the first-person video, he references this.

5. He remained calm. Keeping his cool prevented his fear from resulting in a bad decision.

One thing that he could have done would be to throw objects in the direction of the lion earlier on. This is what appears to be what eventually scares the lion away. However, in the video, it is unclear whether or not Burgess has anything to throw. While there are rocks around him on the ground, bending down to a crouched position can trigger an attack.
