Fly Geyser: Introduction

In 1964, a geothermal energy company drilled a test well in the Hualapai Flat of northern Nevada, hoping to tap underground heat for power generation. When they found the water temperature was not quite hot enough for their purposes, they capped the well and moved on. The cap failed. What emerged over the following decades is one of the most otherworldly landscapes in North America: a constantly erupting fountain depositing vivid mineral cones that grow several inches each year, painted in streaks of brilliant green and red by thermophilic bacteria thriving in the scalding water. This is Fly Geyser, an accident that became a destination, now watched over by the same organization that brings 70,000 people to the Nevada desert each August for Burning Man.

Instead of cool groundwater, they struck geothermal water near boiling temperature. They abandoned the attempt, but over time a calcium carbonate cone formed around that fir...

Thermophilic algae and bacteria flourish in the moist, scalding environment where water exits the geyser at temperatures exceeding 200 degrees Fahrenheit. These extremophiles, organisms ...

Fly Geyser: From Private Mystery to Burning Man Stewardship

Fri, 23 Jan 2026 00:00:00 GMT

Photo credit Jeremy C. Munns, Public domain. For decades, Fly Geyser remained hidden on private ranchland, visible only as a distant curiosity from the highway or in photographs taken by trespassers. The Fly Ranch property encompassed 3,800 acres of remote high desert, and its owners preferred solitude. That changed in June...

Fly Geyser: A Landscape Still Being Built

Fri, 23 Jan 2026 00:00:00 GMT

Photo credit Ken Lund from Las Vegas, Nevada, USA, CC BY-SA 2.0. Unlike natural geysers in places like Yellowstone that erupt periodically, Fly Geyser is a continuously flowing feature, a perpetual fountain building its own monument. The mound of accumulated minerals now stands several feet high and continues growing. The travertine pools surr...

Photo credit Ken Lund, CC BY-SA 2.0. Fly Ranch sits at the edge of the Black Rock Desert, the same playa that hosts the Burning Man festival each year. Gerlach, the nearest town, lies a few miles to the south, a community of a few hundred souls that swells dramatically each August when festival-goers pass through. T...
