Behind a 30 foot waterfall in Chestnut Ridge Park near Buffalo, New York, a small flame flickers year round inside a natural grotto — fuelled by natural gas seeping from rocks that are 400 million years old.
The Eternal Flame Falls is one of fewer than 50 eternal flames in the world. What makes this one scientifically extraordinary is that it shouldn't exist.
Natural gas is typically produced when shale rock is heated to around 100 degrees Celsius — breaking down carbon structures into gas. The shale beneath Eternal Flame Falls is cool, young and shallow by geological standards. It has no business producing natural gas. Yet it does — and scientists believe it may point to a previously unknown geological mechanism for natural gas formation.
The gas itself is unusual too. Normal natural gas is mostly methane. The gas at Eternal Flame Falls contains around 35% ethane and propane — a composition that doesn't match typical shale gas anywhere else in the world.
The Seneca Nation knew about this flame long before Europeans arrived — believed to have used the natural gas seep for heating, lighting or ceremonial purposes for thousands of years. European explorers first documented the gas seeps in the mid-1600s.
The flame can go out — extinguished by heavy rainfall or wind — but is regularly relit by visitors. It has been burning in one form or another for as long as anyone has recorded it.
A flame that science says shouldn't exist. Behind a waterfall. In a New York park.
Would you hike to see it?
