Fly Geyser - Nevada

Fly Geyser, also known as Fly Ranch Geyser is a small geothermal geyser located on private land in Washoe County, Nevada approximately 20 miles (32 km) north of Gerlach. Fly Geyser is located near the edge of Fly Reservoir in the Hualapai Geothermal Flats and is approximately 5 feet (1.5 m) high, by 12 feet (3.7 m) wide, counting the mound on which it sits. In June 2016, the non-profit Burning Man Project announced that they had purchased the Fly Ranch, including the geyser for $6.5 million. The Burning Man Project is planning to provide controlled access to the property in the future and is asking for donations to move the project forward.
There are actually two geysers on the Fly Ranch property. The first was created nearly 100 years ago as part of an effort to make a part of the desert usable for farming. A well was drilled and geothermal boiling water (200 degrees) was hit. Obviously not suitable for irrigation water, this geyser was left alone and a 10 to 12 foot calcium carbonate cone formed.

In 1964 a geothermic energy company drilled a test well at the same site. The water they struck was that same 200 degrees. Hot, but not hot enough for their purposes. The well was supposedly re-sealed, but apparently it did not hold. The new geyser, a few hundred feet north of the original, robbed the first of its water pressure and the cone now lays dry.

This second geyser, known as Fly Geyser, has grown substantially in the last 40 years as minerals from the geothermal water pocket deposit on the desert surface. Because there are multiple geyser spouts, this geyser has not created a cone as large as the first, but an ever growing alien looking mound. The geyser is covered with thermophilic algae, which flourishes in moist, hot environments, resulting in the multiple hues of green and red that add to its out-of-this-world appearance.
