Tucked into a rocky grotto at the base of a small waterfall in Western New York, a flame flickers behind a curtain of falling water. It is only a few inches tall, sheltered in a hollow in the rock, and it burns almost continuously, year after year. Water and fire coexisting in the same spot make the site one of the most unusual natural attractions in the region.
The waterfall is known as Eternal Flame Falls, in the Shale Creek Preserve section of Chestnut Ridge Park south of Buffalo. The flame is fed by natural gas seeping from the bedrock, and while its name overstates matters slightly, since the fire can be blown out and occasionally needs to be relit, it burns often enough and reliably enough to draw a steady stream of hikers to see it for themselves.
A flame that lives behind a waterfall
The flame sits in a small alcove at the foot of the falls, where escaping gas collects in sufficient concentration to stay lit. Visitors who find it dark can often relight it with a lighter, and under good conditions it reaches roughly eight inches in height. Its persistence, tucked into a damp recess just beside cascading water, is what gives the site its striking, almost paradoxical quality.
The attraction was long considered obscure, but growing media attention and trail improvements have sharply increased visitation in recent years. That popularity has brought problems of its own, including litter and erosion, prompting upgrades such as added steps and railing along the challenging descent to the creek bed, as detailed in the record of Eternal Flame Falls.
The gas that feeds the fire
The flame runs on a natural hydrocarbon seep, a spot where gas trapped underground works its way to the surface. Geologists who studied the site in 2013 found that the gas emerging here is chemically distinctive. Compared with typical natural gas seeps, which are dominated by methane, the emissions at Eternal Flame Falls contain an unusually high proportion of ethane and propane, at around 35 percent.
The researchers estimated that the main seep releases roughly one kilogram of methane per day, and they noted numerous smaller “micro seeps” scattered through the surrounding area. By comparing the gas with samples from wells nearby, they traced its origin to the Rhinestreet Shale, a rock layer roughly 400 meters beneath the surface, from which tectonic faulting has allowed the gas to rise.
The seep is therefore not an isolated oddity but the most visible outlet of a broader system of gas escaping through the fractured rock. Its concentration at the base of the falls, where the alcove traps enough gas to stay lit, is what turns a diffuse geological process into a single, watchable flame.
Why the science surprised geologists
The find carried implications well beyond a single novelty flame. Conventionally, shale must be heated to high temperatures, on the order of 100 degrees Celsius, for its carbon compounds to break down into natural gas. The Rhinestreet Shale supplying Eternal Flame Falls is comparatively cool, as well as younger and shallower than typical gas-bearing rock, which means the standard explanation does not fit.
That mismatch suggests some additional, not yet demonstrated process may be generating gas within the shale. One possibility raised by researchers is that a natural catalyst is helping break down the rock’s carbon structures at lower temperatures than expected. If confirmed, such a mechanism would matter for understanding how natural gas forms in the broader environment, turning a curiosity into a small scientific question.
Part of a global family of natural eternal flames
Eternal Flame Falls is not entirely unique. Naturally fueled flames burn at a number of gas seeps around the world, some of which have blazed for centuries and hold religious or cultural significance in their regions. What sets the New York example apart is the intimate pairing of the flame with a waterfall, an arrangement that lets fire and flowing water occupy the same small pocket of rock.
Because the flame depends on a steady supply of seeping gas and on someone occasionally relighting it, its “eternal” character is really a matter of persistence rather than true permanence. The gas continues to rise from the shale, the alcove continues to shelter it, and the flame keeps returning, which is close enough to endless to have earned the name.
Visiting a fragile natural landmark
Reaching the flame requires a hike along a trail that descends into the stream valley, a route steep and slippery enough that officials recommend proper footwear and caution. The 2020s improvements, including box steps and railing, were built partly to protect both visitors and the surrounding terrain from the pressure of rising foot traffic.
The site sits at an interesting intersection of geology, ecology, and recreation. It offers a rare chance to stand beside a flame produced entirely by the earth, while also illustrating how a once-quiet natural wonder can strain under its own growing fame, making stewardship as much a part of its story as the fire itself.
