In 1966, a group of teenagers in the town of Paulding, on Michigan’s Upper Peninsula, reported seeing a ghostly light in a valley nearby. Locals claimed that the light, which appears every night when viewed from a precise location, was the lantern of a ghostly railroad brakeman who had been killed trying to warn an oncoming train of railway cars stopped on the track.
A more prosaic explanation is that the specter is produced by the headlights of cars traveling on US 45, about 5 miles away. In 2010, a group of student engineers from Michigan Tech studied the light with a telescope and distinguished individual vehicles and even an Adopt a Highway sign. They were able to produce the effect themselves by driving a car along the suspected stretch of highway. It’s thought that an inversion layer may create a volume of unusually stable air that accounts for the lights’ visibility at such a distance.
That didn’t end the ghost theory, though. “We’ve been told we haven’t seen the real Paulding Light,” Ph.D. candidate Jeremy Bos told Michigan Tech News in 2010. “I’ve been out there 15 times, hours at a time, in the heat, the cold, and the rain. It’s always the same. We were there Monday with a man who saw the headlights on our computer, and he refused to believe it.”
“No matter what, some people will believe what they want to believe.”
