“Snarly Yow” is the name given to a phantom hound which haunted a section of the National Pike near Turner’s Gap (Frederick County). The hound was first mentioned by Madeleine V. Dahlgren in 1882. Her book South Mountain Magic details no less than a dozen sightings of the beast. One account is from a Daniel Mesick, whose father kicked at a huge dog near Dame’s Quarter. His foot passed directly through it. Sticks, rocks and even bullets were recorded as having passed through the beast in Dahlgren’s accounts. Other accounts have stated that the dog left physical traces and frightened horses to the extent that they threw their riders. The dog was seen numerous times by a minister at a small church in Glendale. A staple of Frederick County legendry for years, the Yow was seen in 1962 near Zittlestown. In this instance, it was headless, white, and drug a chain along behind it.
The South Mountain area is also the traditional home of a number of werewolves.
