Flaming Geyser Hill is a distinctive natural monument nestled within Flaming Geyser State Park in King County, Washington. Situated along the scenic Green River, near the communities of Black Diamond and Auburn, this area is renowned for its unique geological past. It’s best known for the methane seeps that once created a spectacular "flaming geyser" and the still-active "bubbling geyser," both remnants of early 20th-century coal prospecting in the Green River Gorge.
