Fly Geyser

Fly Geyser is a geothermal feature in Washoe County in northwestern Nevada that rises about 25 feet (8 meters) high and continuously erupts hot water from underground sources. The eruption originates from a borehole that tapped into an underground water reservoir during geothermal exploration in 1964.

The feature formed in 1964 when a test well for geothermal energy exploration reached an underground aquifer. The resulting hot water eruption was never sealed and has continued uninterrupted since then.

The site has become a favorite subject for photographers and artists interested in geothermal phenomena and human impact on natural processes. Visitors often come here to experience the connection between chance, energy exploration and landscape transformation.

The site sits on private Fly Ranch land about 20 miles (30 kilometers) north of Gerlach and is accessible only through guided tours organized by Friends of Black Rock-High Rock. Visiting requires planning, as the surrounding area is remote and unpaved.

Thermophilic bacteria and archaea living in the hot water create vivid red, orange, yellow and green mineral deposits that form terraced pools around the eruption vents. The coloring shifts depending on water temperature and mineral composition in different zones.
