About Fly Geyser
Fly Geyser looks as if someone planted a miniature alien landscape in the Black Rock Desert. Hot water continually spills over mineral terraces in shades of orange, green, and yellow, creating a colorful mound that keeps slowly changing. The scene is natural in its growth, but human activity started it.
A geothermal drilling project in the 1960s opened a route for hot water to reach the surface. Minerals accumulated around the flow, while heat-loving algae helped paint the terraces. The result is one of Nevada’s strangest collaborations between accident and geology.
There is one essential catch for visitors: Fly Geyser sits on private Fly Ranch land. It is not a pull-over-and-walk-in attraction. Friends of Black Rock-High Rock offers guided nature walks on selected dates, with advance tickets, and the walk also passes wetlands and art installations.
