The name of Yellowstone National Park's "Mud Volcano" feature and the surrounding area is misleading; it consists of hot springs, mud pots and fumaroles, rather than a true mud volcano. Depending upon the precise definition of the term mud volcano, the Yellowstone formation could be considered a hydrothermal mud volcano cluster. The feature is much less active than in its first recorded description, although the area is quite dynamic. Yellowstone is an active geothermal area with a magma chamber near the surface, and active gases are chiefly steam, carbon dioxide, and hydrogen sulfide. However, there are some Mud Volcanoes and Mud Geysers elsewhere in Yellowstone. One, the "Vertically Gifted Cyclic Mud Pot" sometimes acts as a geyser, throwing mud up to 30 feet high.

Námaskarð, situated 6km east of lake Mývatn at the foothills of the towering mountain Námafjall, is the name popularly given to Iceland’s best-known area of mud pools. The high-temperature geothermal area is more correctly known as Hverarðnd, although sometimes it is called the Námafjall Geothermal Area because of its proximity to the mountain.
Námaskarð earns its notoriety mainly because of its hot bubbling mud pools and sulphurous steam vents (solfataras or fumaroles) which are spread over an area of several acres. At a depth of 1000m, the temperature is above 200o C; even at the surface the mud in the pools can be at a temperature of 80-100o C so they must be approached with caution. The most active mud pools are those with a crater rim around them, formed from the splatter caused by escaping gas bubbles. The pools are not static but evolve over time, with new pools starting up and old ones dying out as the years pass.
The mud pools are like primitive chemical plants. Steam and water, percolating upwards through porous rock to the surface, contain dissolved chemicals and gases, mainly hydrogen sulphide and carbon dioxide. When they react with oxygen in the air, mineral deposits, like sulphur and gypsum, are formed. Iron sulphide, commonly called pyrite, forms in the mud pools, giving them a dull blue-black hue. Also present is sulphuric acid, which breaks down the surrounding soil and rocks, forming sticky clay mud.
The thermal area Hverir (Hverir austan Námaskarðs, or "hot springs east of Námaskarð") sits at the base of the east slope of the volcano Mt. Námafjall. It is full of fumaroles, mud pots, steam, and sulfur-stained earth.
Krýsuvík is a geothermal area on the Reykjanes Peninsula known for its steaming vents, bubbling mud pots, colorful mineral deposits, and volcanic landscapes. The region lies within an active volcanic system and showcases the powerful geothermal forces that shape Iceland. Krýsuvík is one of the most accessible geothermal sites in the country and a popular destination for visitors exploring the unique geology of the Reykjanes peninsula.
Seltún
Seltún is the main geothermal area of Krýsuvík on the Reykjanes Peninsula in southwest Iceland. The site is known for its steaming fumaroles, bubbling mud pools, sulfur deposits, and brightly colored mineral-rich hillsides. Boardwalks allow visitors to explore the active geothermal landscape safely while observing the volcanic forces that continue to shape the region.
Fúlipollur
Fúlipollur ("Stinky Pond") is a small geothermal mud pool within the Seltún area. Its name comes from the strong sulfur smell produced by geothermal gases rising through the water and mud. Surrounded by colorful mineral deposits and steaming ground, it is one of the most photographed features of the Krýsuvík geothermal field and a vivid example of Iceland’s volcanic activity.
Turrialba Volcano is named after the region of Costa Rica in which the volcano is situated in Turrialba County, Cartago of Costa Rica.

Yellowstone National Park is known for its variety of wildlife and - even more - for its many geothermal features like geysers, fumaroles, hot springs etc., the best known of them being the geyser "Old Faithful". Yellowstone National Park is said to be the first National Park of the World. It is inscribed in the World Heritage List of the UNESCO.
---quotation from whc.unesco.org:---
Yellowstone National Park, established in 1872, covers 9,000 km2 of a vast natural forest of the southern Rocky Mountains in the North American west. It boasts an impressive array of geothermal phenomena, with more than 3,000 geysers, lava formations, fumaroles, hot springs and waterfalls, lakes and canyons. It is equally known for its wildlife: grizzly bears, bison, wolves and wapiti, North American elk.
The park is part of the most seismically active region of the Rocky Mountains, a volcanic 'hot spot'. The Yellowstone Plateau, now a forested area of 650,000 ha with an average elevation of 2,000 m, was formed out of the accumulation of rhyolite magma. The plateau is flanked on the north, east and south by mountains that rise to 4,000 m. Crustal uplifts 65 million years ago raised blocks of crust to form the southern Rocky Mountains. After that, volcanic outflows of andesitic composition were common to about 40 million years ago. Andesitic ashflows and mudflows of the Eocene age covered forests, which became petrified. Some 200 species of petrified plant have been found. A more recent period of rhyolitic volcanism began in the region about 2 million years ago, during which time thousands of cubic kilometres of rhyolitic magma filled immense chambers under the plateau and then erupted to the surface. Three cycles of eruption produced huge explosive outbursts of ash. The latest eruptive cycle formed a caldera 45 km wide and 75 km long, when the active magma chambers erupted and collapsed. The crystallizing magma is the source of heat for hydrothermal features such as geysers, hot springs, mud pots and fumaroles.
Yellowstone contains 200-250 active geysers and perhaps 10,000 thermal features. Most of the area was glaciated during the Pleistocene and many glacial features remain. The park lies at the headwaters of three major rivers. Yellowstone River is a major tributary of the Missouri River that flows via the Mississippi to the Gulf of Mexico. Firehole and Gibbon rivers unite to form the Madison, which also joins the Missouri. Snake River arises near the park's south boundary and joins the Columbia to flow into the Pacific. Yellowstone Lake is the largest lake at high elevation (2,357 m) in North America. Lower Yellowstone Falls is the highest of more than 40 named waterfalls in the park.

Lassen Volcanic National Park 686_1 Wikipedia excerpt: Near Little Hot Springs Valley is Bumpass Hell, which is a hydrothermally altered geothermal area that spans 16 acres (65,000 m²) and has hot springs, fumaroles, and boiling mud pots. Never part of Mount Tehama's main vent, Bumpass Hell is the result of fissures that tap the volcanic heat (which is thought to be a cooling mass of andesite, perhaps three miles (5 km) below the surface)
It is named after Kendall Vanhook Bumpass, a miner who worked in the Lassen area in the 1860s. K.V. Bumpass discovered the area and was named on a mining claim for the area. In 1865 the editor of the Red Bluff Independent newspaper took a trip with Bumpass to see the locale. During this trip K.V. Bumpass broke though a thin crust above a boiling mud pot, his leg was badly scalded and eventually had to be amputated. The area was named in his honor.

New Zealand's most active marine volcano - geothermal activity, roaring steam vents and fumaroles, bubbling mud pits, hot volcanic streams and lake of steaming acid. Vivid hues of yellow and orange from abundant sulphur
I have so many interesting abstract-style images of the geothermal features at Yellowstone, but I have to admit I didn't spend a lot of time reading the signs so that I could discriminate one type from another. It's not a cone or geyser, but is it a spring, or fumarole or paint pot ??? dunno - I just know they're beautiful, colorful and fascinating.
Sometimes I get looking at my portrait shots and realize that I intended to stitch something together. This is a five photo stitch because it is just too difficult to get this into a single shot. This area not only has fumaroles, but also frying pans and mud pots. No geysers, however, and that is fine. It is other-worldly to be sure.
These steam plumes are part of Brady's Hot Springs, a hydrothermal area along the Brady Fault in northwestern Nevada. Geothermal energy generation in the area has occurred for many years and the surface hot springs have long been wrecked. The steam plumes ("fumaroles") are not natural - the original hot springs had flowing hot water at the surface, with active siliceous sinter deposition. The current water table is well below the surface. It dropped due to geothermal power development.
People need to understand that geothermal power is NOT GREEN. Brady's Hot Springs have been ruined forever - might as well continue making electricity there. Untapped "hydrothermal resources" need to be left as is. Such environments are among the rarest and most beautiful on Earth (for example, Yellowstone). Geothermal drilling destroys the environment. Overpopulated hominids cannot continue wrecking the Earth's surface environment ad infinitum.
