Fly Geyser is a man-made geyser in the middle of the Nevada Desert and is considered one of the most beautiful attractions in Nevada. Located 20 miles north of Gerlach, in Washoe County (the Nevada desert), it was accidentally created in 1916 during well drilling. The rainbow effect is created by minerals in the water reacting with oxygen in the air. The geyser contains several terraces discharging water into 30 to 40 pools over an area of 30 hectares (74 acres).
Fly Geyser is located on private land, behind a closed gate and a fence topped with barbed wire. It is rarely open to the public but can be viewed from the road.
Geyser
A geyser is a rare kind of hot spring that is under pressure and erupts, sending jets of water and steam into the air. Roughly two-thirds of the world’s geysers are in Yellowstone National Park in the United States. Other geyser hot spots are Siberia, Chile, Iceland and New Zealand.
Geysir (see below photo), sometimes known as The Great Geysir, is a geyser in southwestern Iceland. It was the first geyser described in a printed source and the first known to modern Europeans. The English word geyser derives from Geysir. Wikipedia
