He Was Filming A Moose When It Charged At Him. Split-Second Horror Caught On Camera

This is the terrifying moment a bull moose suddenly charged at a person filming it from a short distance away. A video from Colorado Parks and Wildlife shows the animal going from peaceful to aggressive in the fraction of a second, and it is now being used by park authorities as a warning to curious visitors. "This video is an example of being too close to a bull moose and how quickly they can decide to charge on you," Colorado Parks and Wildlife wrote while sharing the video, which was recorded at Clear Creek County.
