Are Yellowstone geysers powered by hidden heat?
Yes. Yellowstone's geysers need heat, water, pressure, and plumbing beneath the surface.
HOT PLUMBING
The Claim
Yellowstone geysers erupt because groundwater is heated underground.
The Answer
The National Park Service explains that geysers depend on volcanic heat, water supply, a pressure system, and constricted underground channels.
Why This Is Surprising
It sounds like the kind of claim that races around social feeds without context. The source trail matters because the best version of the wonder is the verified one.
How We Checked It
We looked for an authoritative primary source, checked the wording against at least one credible secondary source when available, and recorded the last review date.
