Brown Mountain, North Carolina
The Brown Mountain Lights are one of the most well-known cases of Ghost Lights. The lights are described as red, blue, green, or white balls which disappear when approached. Legend holds that these lights are the spirits of Native American tribesmen killed in battle long ago. Other theories, put forth by such organizations as The U.S. Geological Survey, have at various times suggested that the lights are ignited swamp gas, the reflected lights of local towns, or train/car headlights. However, there is no swampland in the area, and the lights have been seen since long before the time of automobiles and electric lights. Thus the Brown Mountain Lights remain a mystery.
