The Fly Geyser, also known as Fly Ranch Geyser is an accidentally man-made small geothermal geyser located in Washoe County, Nevada. It is located approximately 20 miles (32 km) north of Gerlach. The Fly Geyser is located near the edge of Fly Reservoir. The geyser itself is only about 5 feet (1.5 m) high. If you include the mound it sits on, it stands a total of 12 feet (3.7 m) in height.
The Fly Geyser is located on the private Fly Ranch in Hualapai Flat, about 0.3 miles (0.48 km) from State Route 34. The ranch is privately owned. There is a high fence and a locked gate topped with spikes to exclude trespassers. The only access is a dirt road, but the Fly Geyser is large enough to be seen from the road.
Fly Geyser Origins
The Fly Geyser is not an entirely natural phenomenon. It was accidentally created in 1964, when a well was dug as part of an exploration for geothermal energy. It is not known whether the well was not capped correctly, or left uncapped. Regardless of which was the case, dissolved minerals began rising and accumulating. This led to the creation of the travertine mound on which the geyser sits and continues to slowly grow. Superheated water is continuously released. The triple spumes reach 5 feet (1.5 m) into the air. The Fly Geyser contains several terraces discharging water into 30 to 40 pools over an area of 74 acres (30 hectares).
Fly Geyser Nature
The geyser mound is composed of a series of different minerals, but its incredible colors are due to thermophilic algae, making it most visually impressive. A prior well-drilling attempt in 1917 resulted in the creation of a man-made geyser close to the currently active Fly Geyser. This earlier drilling created a pillar of calcium carbonate about 12 feet (3.7 m) tall, but it 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) tall.
