The town of Avilla in Jasper County, Missouri, sits along historic Route 66 and has gained a reputation as one of the most haunted locations on the Mother Road. Avilla has experienced significant depopulation over the decades, and its abandoned and decaying structures have become the setting for widespread reports of Shadow Folk — dark, human-shaped silhouettes that move through the empty buildings and along the town's streets at night. Witnesses describe the figures as solid black shapes, darker than the surrounding darkness, that glide rather than walk and seem aware of observers, sometimes turning to face them before vanishing. The Shadow Folk are most frequently reported near the town's abandoned church and along the main road through town. Some visitors have also described hearing whispered conversations in an unintelligible language, the sound of horses and wagons on the empty road, and the smell of wood smoke when no fires are burning. The town's decline began after Route 66 was bypassed by the interstate, and some investigators have connected the paranormal activity to the town's collective sense of abandonment and loss. Others point to Avilla's proximity to Civil War battle sites and to lead and zinc mining operations that scarred the landscape.
