The Niles Canyon ghost is an urban legend within the vanishing hitchhiker archetype, about the ghost of a girl who had died in a car accident. The accident is said to have taken place on February 28, with the year varying, and the ghost is said to walk the road on that day every year, looking to hitch a ride to San Francisco. Another version of the story has the ghost described as a White Lady killed in a carriage accident a hundred years previously.
