Diana's Punchbowl: Nevada's “Devil's Cauldron” — Look, But Never Soak
Diana's Punchbowl is one of the strangest geothermal formations in the American West: a travertine dome rising out of the Nevada desert with a turquoise pool hidden in its crater — water far too hot to ever enter.
You can look at Diana's Punchbowl, but you can never soak in it. The bowl's turquoise water is estimated at roughly 141–200°F — hot enough that a fall would likely be fatal — and the dome sits on private ranch land where access is permitted but revocable at any time.
Current Status at a Glance
Unlike most entries in our closed & dangerous hot springs list, Diana's Punchbowl isn't closed by an agency order — it was simply never a soaking spring. Access details per onX and Nevada hiking sources:
| Land status | Private ranch land — Monitor Ranch |
| Access | "Currently permitted, revocable" per onX — a courtesy, not a right; posted signs take precedence |
| The formation | Travertine dome ~600 ft in diameter and ~75 ft tall; a ~50-ft-wide bowl ~30 ft deep holds the turquoise pool below the rim |
| Water temperature | Measured 123–141°F in 1974; some estimates up to ~200°F — treated here as a range |
| Soaking | Never possible in the bowl. Outflow creek pools run ~100°F but are small and unreliable |
| Safety record | Zero confirmed deaths — but a fall into the bowl would likely be fatal |

The Dome, the Name & the Screaming-Sounds Legend
Diana's Punchbowl is a travertine dome — mineral deposits built up by the spring over time into a mound roughly 600 feet across and 75 feet tall. Near the top, a bowl about 50 feet wide drops some 30 feet to a startlingly blue-green pool. That sight — steaming turquoise water cradled in a rock crater — earned it the darker nickname the Devil's Cauldron.
- Geologic era → today: Mineral-laden geothermal water deposits travertine layer by layer, building the dome that now dominates this stretch of central Nevada ranch country.
- 1974: The pool is measured at 123–141°F. Later estimates push the figure as high as ~200°F — sources conflict, so treat it as a range with a lethal floor.
- August 2020: YouTuber TechRax lowers an iPhone toward the pool on video. The recording picks up screaming-voice-like sounds, and the clip goes viral — giving the Punchbowl a second fame as a paranormal hotspot.
- Today: The site draws curious travelers down lonely Nevada highways — all of them there to look at something they must never touch.
Can You Visit Diana's Punchbowl?
Yes — to look. The dome sits on the private Monitor Ranch, and onX describes access as “currently permitted, revocable.” That means visitors are generally tolerated, but the permission is a courtesy that can end at any time. If you go, treat it like the private property it is:
- Obey any posted signs or gates — they override any general "access permitted" guidance, and ignoring them is trespassing.
- Keep well back from the bowl's rim. Travertine crust can be slick and unstable; a fall into the pool would likely be fatal.
- Never attempt to enter the water — not the bowl, and not even a cautious toe-dip. The temperatures involved scald on contact.
- Don't plan a soak around the outflow. The creek below the dome holds pools around ~100°F, but they are small, seasonal, and unreliable — a bonus, never a destination.
- Leave no trace. Continued access depends on visitors not giving the ranch a reason to revoke it. See our Leave No Trace hot springs guide.

Diana's Punchbowl FAQ
Can you swim in Diana's Punchbowl?
No — never. The pool inside the bowl was measured at 123–141°F in 1974 and some estimates put it near 200°F, far beyond survivable soaking temperatures. The bowl is roughly 30 feet deep with a pool below the rim, and a fall in would likely be fatal. Diana's Punchbowl is strictly a look-at-it formation.
Has anyone died at Diana's Punchbowl?
There are zero confirmed deaths on record — which is remarkable given how dangerous the site is. "A fall would likely be fatal" is the honest framing, and the fact that the record is still clean is the real story, not a reason to test it.
Is Diana's Punchbowl on private land?
Yes. The dome sits on private ranch land — the Monitor Ranch. Access is described by onX as "currently permitted, revocable": visitors are generally tolerated, but that permission can be withdrawn at any time, and posted signs or gates take precedence.
Why is it called the Devil's Cauldron?
The nickname comes from the sight and heat of it: a turquoise, steaming pool sitting inside a ~50-foot-wide bowl atop a ~75-foot travertine dome — a literal cauldron of near-scalding water rising out of the Nevada desert.
What is the screaming-sounds legend at Diana's Punchbowl?
In August 2020, YouTuber TechRax lowered an iPhone toward the pool on video, and the recording picked up screaming-voice-like sounds. The clip went viral and gave the Punchbowl a paranormal reputation — part of why it draws curious visitors today.
How hot is the water in Diana's Punchbowl?
The pool was measured at 123–141°F in 1974, and some sources estimate it may reach around 200°F. Either end of that range is lethal — for comparison, water above ~106°F already exceeds safe soaking limits.
