(FOX NEWS) A video has popped up on YouTube which purportedly shows a UFO zigzagging over the Yellowstone volcano.

The choppy video, which is more than 3 minutes in length, appears to show a metallic object in the sky. A bright light emerges from the object for a few seconds and then it speeds off into the distance. The video was taken on June 9, but only recently uploaded to the video-sharing site.
