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 with an intermittent discharge of water ejected turbulently and accompanied by steam. The formation of geysers is fairly rare, and is caused by particular hydrogeological conditions that exist only in a few places on Earth.
The Old Faithful Inn is a hotel in the western United States with a view of the Old Faithful Geyser, located in Yellowstone National Park, Wyoming. The Inn has a multi-story log lobby, flanked by long frame wings containing guest rooms. In the western portion of the park, it sits at an approximate elevation of 7,350 feet (2,240 m) above sea level.
Old Faithful is a cone geyser in Yellowstone National Park in Wyoming, United States. It was named in 1870 during the Washburn–Langford–Doane Expedition and was the first geyser in the park to be named. It is a highly predictable geothermal feature and has erupted every 44 minutes to two hours since 2000. The geyser and the nearby Old Faithful Inn are part of the Old Faithful Historic District.
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.
Solitary Geyser is a fountain-type geyser in Yellowstone National Park, located above the Upper Geyser Basin. Eruptions last about a minute and are four to eight minutes apart; most eruptions are less than six feet in height. It is very distinctive with clear blue water underneath and a base that is tinted orange. Solitary Geyser is accessible via the Observation Point loop trail behind Old Faithful.
Big Cub 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.
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.
Doublet Pool is a hot spring in the Upper Geyser Basin of Yellowstone National Park, Wyoming.
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.
Lone Star Geyser is a cone type geyser located in the Lone Star Geyser Basin of Yellowstone National Park. The basin is a backcountry geyser basin located 3 miles (4.8 km) southeast of Old Faithful Geyser and the Upper Geyser Basin. The geyser is reached via an old service road open to hikers and biking with the trailhead near Kepler Cascades on the Grand Loop Road.
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.
Ear Spring is a hot spring in the Upper Geyser Basin of Yellowstone National Park in the United States. Located close to Old Faithful, on rare occasions Ear Spring will erupt as a geyser, and can shoot rocks and debris as well as water more than 25 feet (7.6 m) for a few minutes. On September 15, 2018, Ear Spring was seen on the National Park Service webcam at Old Faithful erupting for a minute and reached heights of 20 to 30 ft. This was the largest eruption the pool may have had since 1957. The eruption tossed small rocks out along with trash that people had thrown in it over the years and the heated water killed the surrounding bacterial mats that normally thrive in less heated conditions. Likely related to the eruption of Ear Spring, a new thermal feature opened up under the pedestrian boardwalk near Pump Geyser which resulted in the National Park Service temporarily closing off the boardwalk. This new thermal feature was spouting water the night of September 18-19, 2018. Additionally, Doublet Pool and North Goggles Geyser have both been more active in the period immediately after the rare eruption of Ear Spring.
