Analysis : Fly Geyser
Posted July 1, 2011on:
Fly Geyser, also known as Fly Ranch Geyser is a small geothermal geyser that is located approximately 20 miles (32 km) north of Gerlach, in Washoe County, Nevada. The Geyser is located in Hualapai Flat less than a mile from State Route 34. The Geyser is about 1/3 miles from the road and is large enough to be seen from the road.
Fly Geyser is located on the private Fly Ranch and is accessible only by a small private dirt road. The ranch is currently owned by Todd Jaksick. There is a high fence and a locked gate with several metal spokes on the top to keep trespassers out, but despite the booby traps, many people still prefer to jump the fence to get a better look. Several organizations have tried to purchase the land for conservation, and make it open to the public, but have been denied.
Fly Geyser is a very little known tourist attraction, even to Nevada residents. It is located right near the edge of Fly Reservoir and is only about 5 feet (1.5 m) high, (12 feet (3.7 m) if you count the mound on which it sits). The Geyser is not an entirely natural phenomenon, and was accidentally created in 1916 during the drilling of a well. The well functioned normally for several decades, but then in the 1960s geothermally heated water found a weak spot in the wall and began escaping to the surface. Dissolved minerals started rising and piling up, creating the mount on which the geyser sits, which is still growing to date. Today, water is constantly squirting out reaching 5 feet (1.5 m) in the air. The geyser contains several terraces discharging water into 30 to 40 pools over an area of 30 hectares (74 acres). The geyser is made up of a series of different minerals, including sulfur dioxide, which gives it its magnificent coloration.
There are two additional geysers in the area that were created in a similar way as Fly Geyser. The first geyser is approximately 3 feet high and is shaped like a miniature volcano. The second geyser is cone shaped and is of the same approximate size as Fly Geyser. Like Fly Geyser, these geysers are continually growing.
The desert has numerous volcanic and geothermal features of the northwest Nevada volcanic region, including two Black Rock Points (west and east) at the southern end of the Black Rock Range and which have dark Permian volcanic rocks similar to another Permian black diabase dike formation in Nevada.
The portion of the Lake Lahontan lakebed in the Black Rock Desert is generally flat with Lahontan salt shrub vegetation, widely-scattered hot springs, and a playa. In areas of the lakebed along mountains, rain shadow results in desert precipitation levels.
The continuous Fly Geyser of Fly Ranch is on private land and began during 1916 water well drilling that accidentally penetrated a geothermal source.
The playa of the Black Rock Desert lakebed is ~200 sq mi (520 km2) within an area bounded by the Calico Mountains Wilderness (north), Gerlach (west), the Applegate National Historic Trail (northeast), and the Union Pacific Railroad (south). The “South Playa” (~30 sq mi, with ~13 sq mi (34 km2) in Washoe Co) is between Gerlach and the southwest boundary of the National Conservation Area (NCA), while the northeast NCA portion of the playa (including ~25 sq mi (65 km2) in Humboldt Co) is between the NCA boundary and the Applegate National Historic Trail. A Nobles route between Gerlach and Black Rock Hot Springs extends through the length of the playa. The playa’s Quinn River Sink of ~3 sq mi (7.8 km2) is where the Quinn River discharges/evaporates ~2.75 miles (4.43 km) south-southwest of Black Rock Hot Springs.
Prospecting and mining has occurred in the Black Rock region since the mid-19th century. US Gypsum Corporation operated a gypsum mine and drywall (brand named Sheetrock) manufacturing plant in Empire, which employed 107 people and produced 266,300 tons of gypsum in 2008.
Allied Nevada Gold Corporation re-opened the Hycroft Gold Mine in 2008 after acquiring it from Vista Gold Corp. Hycroft is a strip-mining operation in the Kamma Mountains near Sulphur on the east side of the Black Rock Desert. An opal mine is in the base of the Calico Mountains on the west side of the desert.
