Ozark Spooklight?

 Hornet Spooklight, Missouri

The Hornet Spooklight can occasionally be spotted along a four-mile stretch of rural road (nicknamed 'Devil's Promenade') on Route 66, located in northeastern Oklahoma but mostly seen from the east in Missouri. The mysterious glowing orb has baffled people for more than a hundred years, and we still don't know exactly what it is or what causes it; some say it's a ghostly spirit, while others claim it's a combination of car headlights and a change in air densities. 

Even the Army Corps of Engineers once tried to pinpoint the cause of the floating orb. They traveled to the area outside Joplin, a town now known as the 2011 site of a devastating F5 tornado, to study the Spook Light in the early 1940s.

They were unable to come to any conclusions.

Guesses as to its origins run from everyday expulsions of gas from the areas abundant shale deposits to UFOs.

Local legend has it that the first to see the lights were the local Quapaw Indians, and some stories saw the light is actually the tormented spirits of two Quapaw lovers run off a cliff by an angry Chieftan.

Other folklore says the light is the torch of a Quapaw or Osage Indian who was beheaded and is searching for his head. Still others maintain it's the spirit of a decapitated miner or Confederate soldier in search of his lost head.

And for every story behind the lights, there's another name for them. It has been referred to as the Hornet Ghost Light, Devil's Jack-O'-Lantern, Ozark Spook Light, and Joplin Ghost Light.

Regardless of the tale behind it or its proper name, the locals who've seen the phenomenon are adamant it is real.

Roberta Williams from Carthage, Missouri has seen the light and told her story to Mysterious Universe.
