Flaming Geyser State Park is a 503-acre day-use park with more than 3 miles of freshwater shoreline on the Green River. The park is centered around a unique geological feature, a “flaming geyser,” or cluster of once-active methane seeps. The flame no longer burns because of the depletion of its methane source. But the history of the flame, told in interpretive panels at the location, will pique park goers’ curiosity about the living nature of planet Earth.
