Brown Mountain lights
Videos
The Brown Mountain lights are purported ghost lights near Brown Mountain in North Carolina. The earliest published references to strange lights there are from around 1910, at about the same time electric lighting was becoming widespread in the area. In 1922, a USGS scientist, George R. Mansfield, used a map and an alidade telescope to prove that the lights that were being seen were trains, car headlights, and brush fires, which ended widespread public concern.
