P = Pennsylvania
Our tour stops in an odd place off of Route 61 in Columbia County. Be prepared there will be no amenities. There is a town in Pennsylvania and the population is 12. Welcome to the ghost town of Centralia, PA.
"This was a world where no human could live, hotter than the planet Mercury, its atmosphere as poisonous as Saturn's. At the heart of the fire, temperatures easily exceeded 1,000 degrees Fahrenheit [540 degrees Celsius]. Lethal clouds of carbon monoxide and other gases swirled through the rock chambers."— David DeKok, Unseen Danger: A Tragedy of People, Government, and the Centralia Mine Fire (University of Pennsylvania Press, 1986) Taken from Wiki
From the quote above it sounds like hell on earth. Today very few homes remain, and after 50 years the fire still burns. The area looks like a field with paved streets with smoke that still billows up from the ground.
