The Hornet Spooklight is a mysterious light that appears in a small area known locally as the "Devil's Promenade" on the border between southwestern Missouri and northeastern Oklahoma west of the small town of Hornet, Missouri. Even though it is named after a small, unincorporated community in Missouri from which it is most commonly reached, the light is most commonly described as being visible from inside the Oklahoma border looking to the west. And as a result, the light goes by many names including The Hollis Light and Joplin Spook Light.
