This is a list of notable geysers, a type of erupting hot spring.
The following are carbon dioxide-generated cold water geysers:
A geyser is a spring characterized by an intermittent discharge of water ejected turbulently and accompanied by steam. As a fairly rare phenomenon, the formation of geysers is due to particular hydrogeological conditions that exist only in a few places on Earth.
The geothermal areas of Yellowstone include several geyser basins in Yellowstone National Park as well as other geothermal features such as hot springs, mud pots, and fumaroles. The number of thermal features in Yellowstone is estimated at 10,000. A study that was completed in 2011 found that a total of 1,283 geysers have erupted in Yellowstone, 465 of which are active during an average year. These are distributed among nine geyser basins, with a few geysers found in smaller thermal areas throughout the Park. The number of geysers in each geyser basin are as follows: Upper Geyser Basin (410), Midway Geyser Basin (59), Lower Geyser Basin (283), Norris Geyser Basin (193), West Thumb Geyser Basin (84), Gibbon Geyser Basin (24), Lone Star Geyser Basin (21), Shoshone Geyser Basin (107), Heart Lake Geyser Basin (69), other areas (33). Although famous large geysers like Old Faithful are part of the total, most of Yellowstone's geysers are small, erupting to only a foot or two. The hydrothermal system that supplies the geysers with hot water sits within an ancient active caldera. Many of the thermal features in Yellowstone build up sinter, geyserite, or travertine deposits around and within them.
A mudpot, or mud pool, is a type of acidic hot spring, or fumarole, with limited water. It usually takes the form of a pool of bubbling mud, as a result of the acid and microorganisms decomposing surrounding rock into clay and mud.
Steamboat Geyser, in Yellowstone National Park's Norris Geyser Basin, is the world's tallest active geyser. Steamboat Geyser has two vents, northern and southern, approximately 20 feet (6.1 m) apart. The north vent is responsible for the tallest water columns; the south vent's water columns are shorter.
Whakarewarewa is a Rotorua semi-rural geothermal area in the Taupō Volcanic Zone of New Zealand. This was the site of the Māori fortress of Te Puia, first occupied around 1325, and known as an impenetrable stronghold never taken in battle. Māori have lived here ever since, taking full advantage of the geothermal activity in the valley for heating and cooking.
Steamboat Springs is a small volcanic field of rhyolitic lava domes and flows in western Nevada, located south of Reno. There is extensive geothermal activity in the area, including numerous hot springs, steam vents, and fumaroles. The residential portions of this area, located mostly east of Steamboat Creek and south of modern-day SR 341, are now known simply as Steamboat.
Orakei Korako is a highly active geothermal area most notable for its series of fault-stepped sinter terraces, located in a valley north of Taupō on the banks of the Waikato River in the Taupō Volcanic Zone, New Zealand. It is also known as "The Hidden Valley".
The Ōhakuri Dam is a dam and hydroelectric power station on the Waikato River, central North Island, New Zealand, midway between Taupō, Rotorua and Hamilton. Its dam is about 5 kilometres (3.1 mi) upstream of the Atiamuri Dam.
Sapareva Banya is a town in southwestern Bulgaria, part of Kyustendil Province. As Ancient Germania, a former bishopric, it is a Latin Catholic titular see.
Bijou Geyser is a geyser in the Upper Geyser Basin of Yellowstone National Park in the United States.
Giant Geyser is a cone-type geyser in the Upper Geyser Basin of Yellowstone National Park in the United States. Giant Geyser is the namesake for the Giant Group of geysers, which, on its platform, includes Bijou Geyser, Catfish Geyser, Mastiff Geyser, the "Platform Vents," and Turtle Geyser. Giant Geyser's Platform, a raised stone structure incorporating all these geysers. Giant is notable for its spectacular, but sporadic eruptions, as well as for its very large cone of geyserite, which stands about 12 feet tall.
Mineral spas are spa resorts developed around naturally occurring mineral springs. Like seaside resorts, they are mainly used recreationally although they also figured prominently in prescientific medicine.
Lake Ohakuri, at 12 square kilometres (4.6 sq mi), is the largest artificial lake of the Waikato river system in New Zealand. It forms the reservoir for the Ōhakuri hydroelectric power station. Construction of the dam, approved in 1955, began in 1956 and was completed in 1960. The lake was filled over 14 days in January and February 1961. This drowned two thirds of the Orakei Korako geothermal area, including two of the world's largest geysers, Minginui Geyser and Orakei Korako Geyser.
The following articles relate to the history, geography, geology, flora, fauna, structures and recreation in Yellowstone National Park.
Grotto Geyser is a fountain-type geyser located in the Upper Geyser Basin in Yellowstone National Park in the United States. Grotto Geyser is the namesake for the group of geysers that includes Grotto Fountain Geyser, South Grotto Fountain Geyser, Indicator Spring, Spa Geyser, Startling Geyser, and Rocket Geyser.
Located in a geologically active region, New Zealand has numerous geothermal features, including volcanoes, hot springs, geysers and volcanic lakes. Many of these features cluster together geographically, notably throughout the central North Island's Taupō Volcanic Zone. These areas attract scientific interest and tourism; power generators, industry and civil engineering also utilise them.
The Volcano Park in Mayen-Koblenz is a geopark in the rural district of Mayen-Koblenz in the eastern Vulkan Eifel, Germany. It was founded in 1996 and wraps around the Laacher See. Together with the Volcano Park, Brohltal/Laacher See and the Vulkan Eifel Nature and Geo-Park, it forms part of the national Eifel Volcano Land Geo-Park. The three parks are connected by the 280-kilometre-long German Volcano Route.
The Wallender Born or Wallenborn is a cold water geyser in the village Wallenborn. It is adjacent to the reactivated Andernach Geyser an active cold water geyser in Germany.
Andernach Geyser is the highest cold-water geyser in the world, reaching heights of 30 to 60 metres. The geyser was first bored in 1903 on the Namedy Peninsula in the Rhine near Andernach. In 2006 it was turned into a tourist attraction and one of the sights in the volcano park and part of the Geopark Vulkanland Eifel.
Elk Mountain is a summit in Routt County, Colorado. The mountain lies to the northwest of Steamboat Springs and is easily seen from the city, especially from along Lincoln Avenue, Steamboat's main street. The mountain is also easily seen from Mount Werner, the home of the Steamboat Ski Resort.
