A video taken by a couple in Idaho has captured the attention of hundreds of thousands of people on Facebook. 

The video shows a buck and a mountain lion in a life-or-death battle on the side of a dark, rural road. The video is only about a minute but Michelle Hayden, one of the people in the car, said she believed the battle had been going for awhile before they saw the two animals. 

“All of a sudden we saw this big buck and we couldn’t figure out what on earth it was doing. Finally, we just stopped to see because it kept darting out into the road and then going off on to the bank. So we just kind of slowed down and it didn’t take us long after we had stopped to realize what it had dangling from its neck,” Michelle said to  EastIdahoNews.com.
