Fly Geyser: Nevada’s Colorful Geothermal Wonder

In the middle of the stark Nevada desert, an extraordinary formation rises from the ground like something from another planet, surrounded by mostly open playa, sagebrush, and distant mountains. Fly Geyser is a small geothermal wonder covered in vivid shades of red, orange, green, and yellow, with hot water constantly spilling over its mineral-encrusted terraces.

What makes Fly Geyser even more unusual is that it is not entirely a natural formation. Its story began with human drilling, but geothermal water, minerals, and microorganisms gradually transformed the site into the spectacular formation seen today. 

Located on Fly Ranch in northern Nevada, near the small community of Gerlach and the Black Rock Desert, Fly Geyser has become one of Nevada's most unusual natural attractions.

What Is Fly Geyser?

Fly Geyser, also called Fly Ranch Geyser, is a geothermal formation on private Fly Ranch in Washoe County, Nevada. Hot water rises from underground and flows continuously over a series of terraces, leaving behind layers of minerals and creating the mound-like structure. The colours are what make the geyser particularly striking. Instead of the plain white or grey appearance associated with many geothermal deposits, Fly Geyser displays strong shades of orange, red, green, and yellow.

According to Travel Nevada, the colourful appearance is due to algae that thrive in the hot, moist environment around the geyser. The geothermal water also deposits minerals that gradually build up the terraces. From a distance, the formation looks almost unreal: several rounded towers rise from the desert floor while streams of hot water run down their sides.

Where Is Fly Geyser Located?

Fly Geyser is located at Fly Ranch in northern Nevada, approximately 20-plus miles north of Gerlach. The property lies close to the Black Rock Desert and Hualapai Flat, an area famous for its vast, open desert landscape and its connection with Burning Man.

Fly Ranch itself covers about 5.6 square miles, or roughly 3,800 acres. The property contains wetlands, springs, grasslands, and other unusual desert habitats in addition to the geyser. The official Fly Ranch website describes it as a sanctuary for plants and animals as well as the home of the Fly Geyser hot springs. The contrast is part of the attraction. Around Fly Geyser is an expansive, dry desert, while the geyser produces a small oasis of hot water and vegetation.

How Did Fly Geyser Form?

A Geyser Created by Drilling

The history of Fly Geyser is one of the strangest parts of the story. Fly Geyser is often described simply as a natural wonder, but its present form began with human drilling activity. According to the Burning Man Project, a well was drilled in 1964 while searching for geothermal energy. The well was apparently not capped properly, allowing hot geothermal water to escape continuously.

Over the years, the escaping water deposited minerals around the opening. As the deposits accumulated, they formed the terraces and cone-shaped structures that are so distinctive of Fly Geyser today. So while the geothermal heat and underground water are natural, the event that created the opening was connected to human activity.

How the Colours Developed

The unusual colours of Fly Geyser come from a combination of mineral deposits and microorganisms that live in the hot, wet environment. Water continually flows over the terraces, leaving behind dissolved minerals. At the same time, algae and other microorganisms thrive in the warm conditions. These processes produce the vivid layers of colour that cover the formations. The result is a landscape that seems almost painted. Depending on the light, the formations can appear intensely red, orange, green, yellow, or brown.

Fly Geyser and Fly Ranch

Fly Geyser is only one part of the larger Fly Ranch landscape. The property contains wetlands, natural springs, grasslands, and desert habitats, creating an unusual contrast with the surrounding arid landscape. The official Fly Ranch website describes the area as a place where art, ecology, community projects, and environmental work come together.

The property's connection with Burning Man also adds another chapter to its story. In 2016, the Burning Man Project purchased Fly Ranch, a property that the organisation then described as approximately 3,800 acres and located north of Gerlach. The organisation said the ranch would provide a year-round setting for projects, art, experimentation, and community participation. That relationship is still reflected in the way Fly Ranch is managed and presented today.

Why Is the Fly Geyser So Colourful?

There is no single ingredient responsible for the geyser's extraordinary appearance.

Three processes work together:

  1. Geothermal water continually emerges from underground.

  2. Minerals carried by the water accumulate around the outlets and form terraces.

  3. Algae and other microorganisms grow in the warm, wet conditions, contributing to the vivid colours.

Travel Nevada specifically notes the role of colourful algae in the geyser's appearance. The formations also continue to change. As mineral deposits accumulate and water finds slightly different paths across the terraces, the appearance of the geyser can evolve.

Can You Visit Fly Geyser?

Yes, but Fly Geyser is not a freely accessible roadside attraction.

It stands on private Fly Ranch property, so visitors should not simply leave the highway and attempt to approach the geyser independently. The current Fly Ranch website provides visitor information and a survival guide, including directions and instructions for people arriving for scheduled activities.

Because access arrangements can change, anyone planning a visit should check the official Fly Ranch website before travelling. This is particularly important in the Nevada desert, where summer heat, limited services, and remote roads can make an unplanned visit difficult.

What Makes Fly Geyser Different?

Fly Geyser is unusual for a reason that goes beyond its appearance. It occupies an interesting middle ground between geology and human history. The geothermal heat beneath the ground is natural. The mineral-rich water is natural. The algae and desert ecology are natural. Yet the drilling that created the opening that became today's geyser was caused by human activity. That combination makes Fly Geyser different from a completely natural geothermal feature. It is also a reminder that landscapes do not always develop according to a simple natural-versus-manmade distinction. Sometimes human intervention starts a process that nature then reshapes for decades.

Frequently Asked Questions

Is Fly Geyser completely natural?

No. Fly Geyser's geothermal activity is natural, but the present geyser developed after drilling in 1964 for geothermal energy. The Burning Man Project says the well was likely not properly capped, allowing geothermal water to escape.

Where is Fly Geyser in Nevada?

Fly Geyser is located on Fly Ranch in northern Nevada, north of Gerlach and near the Black Rock Desert region.

Why is Fly Geyser red and green?

Its colours come from a combination of mineral deposits and microorganisms, including colourful algae that thrive in the hot, moist geothermal environment.

Can tourists visit Fly Geyser?

Access is controlled because Fly Geyser is located on Fly Ranch property. Visitors should check the official Fly Ranch information for current opportunities and access requirements before travelling.

Who owns Fly Ranch?

The Burning Man Project purchased Fly Ranch in 2016. Its later financial reporting states that the property was transferred to Future Man LLC, a holding company owned by Burning Man Project, while activities continue to be managed by the organisation.

Conclusion

Fly Geyser is one of Nevada's most unusual geothermal landscapes, not only for its brilliant colours but also for the strange history behind its creation. What began as a geothermal drilling operation eventually became a constantly changing formation of mineral terraces, hot water, and colourful microorganisms.

Set against the vast landscape of northern Nevada, the geyser looks almost impossible to be real. Yet its unusual appearance is the result of understandable geological and biological processes—combined with an accidental beginning caused by human drilling.

Today, Fly Geyser remains the centrepiece of Fly Ranch, an unusual desert property that has developed a new connection with conservation, art, and community projects. For anyone fascinated by strange geology and unexpected landscapes, it is a remarkable example of how nature can transform something humans accidentally set in motion.
