Fly Geyser, also known as Fly Ranch Geyser is a man-made small geothermal geyser located in Washoe County, Nevada. On a small, private ranch in Washoe County, Nevada, you will find this alien, rainbow, mound-like geyser spouting from a geothermal water pocket. What’s interesting is that this geyser is man-made. Accidentally. It is one of two geysers found on the property. The first, also man-made, was created in an attempt to make barren desert usable for farming. Drilling into the ground, a geothermal pocket of 200-degree water was hit, and then left alone because the water was unsuitably hot. The ignored well grew into a calcium carbonate cone. The ranch is private property and generally off-limits to visitors due to vandalism concerns, but it is possible to get in touch with the property owners and organise a tour.
