Fly Ranch Geyser: Nevada’s Marvellous And Unique Oddity

MessageToEagle.com – One of the planet’s most unique oddities can be admired near the small town Gerlach, located approximately two hours north of Reno in northwestern Nevada.

It’s an amazing man-made geothermal geyser, known as Fly Ranch Geyser. Over the years, dissolved minerals created the mound that water now spews up to five meters from.

Approximately 20 miles northeast of the tiny town of Gerlach, Nev., lies one of the planet's rarest oddities: a man-made geyser.

The Fly Geyser is situated  on Fly Ranch, a private property, so it’s not open to the public.

It was accidentally created by well drilling conducted in 1964 by a company searching for a geothermal power in the area. The groundwater, however, turned out not to be sufficiently hot to be tapped for geothermal power, it did have a temperature of more than 200 degrees.

According to later sources, the well was either left uncapped or was improperly plugged and the scalding water has erupted from the well since then, leaving calcium carbonate deposits growing at the rate of several inches per year.

In about 1917, a well was drilled a few hundred feet north of the geyser. This well was also abandoned and, over time, a massive 10 to 12-foot calcium carbonate cone formed. Credits: Alamy

Water is constantly released, reaching 5 feet (1.5 m) in the air. The geyser, which is made up of a series of different minerals, contains several terraces discharging water into 30 to 40 pools over an area of 74 acres (30 ha).

The beautiful red and green colors on the mounds originate from thermophilic algae – microorganisms thriving in the extreme micro-climate of the geysers.

A prior well-drilling attempt in 1917 resulted in the creation of a man-made geyser close to the currently active Fly Geyser; it created a pillar of calcium carbonate about 12 feet (3.7 m) tall, but ceased when the Fly Geyser began releasing water in 1964.

Two additional geysers in the area were created in a similar way and continue to grow. The first geyser is approximately 3 feet (0.91 m) and is shaped like a miniature volcano; the second is cone-shaped and is about 5 feet (1.5 m).
