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.

Difficult to know which one of these kicks out more energy.......at least the one on the right doesn't smell like bad eggs (usually...)
The hot springs of Bath are best known for the constant flow of hot water that emerges in the city centre.
Less well known (apart from the placename it imparts) is the spring that flows from the bed of the tidal Avon in Hotwells, Bristol.
The fumarole of Bathwick Hill is perhaps Bath's most curious geological feature, and it has an unlikely history, as no records of it exist prior to the collapse of the ill-fated Lyncombe Vale spa building around two thirds of a mile to the west - unwisely built directly above the spring from which it intended to profit.
Subsequent to this collapse, the Bathwick fumarole was first seen to emerge beneath a privy at the foot of the garden of one of the villas on Bathwick Hill. (These privies are often known by the local name 'Ajax' after the first of their kind at Kelston*.)
This fumarole is usually inconspicuous, but at times of low temperature and high pressure, it occasionally bursts forth, emitting a cloud of vapour that, trapped beneath a temperature inversion on the north facing slopes there, condenses to form a spectacular cloud. If you witness this, you should count yourself as extremely fortunate.
Here, the fumarole is seen to be in full flow, perhaps encouraged by the low temperatures (-6 degrees centigrade) of the morning of the 2nd February 2012.
*This example was first excavated in the early seventies by the De Cordele family, residents of Kelston at that time.
Mud Volcano and Sulphur Caldron are primarily mud pots and fumaroles because the area is situated on a parched water system with little water available. Fumaroles or "steam vents" occur when the ground water boils away faster than it can be recharged. Also, the vapors are rich in sulfuric acid that leaches the rock, breaking it down into clay. Because no water washes away the acid or leached rock, it remains as sticky clay to form a mud pot. Hydrogen sulfide gas is present deep in the earth at Mud Volcano. As this gas combines with water and the sulfur is metabolized by cyanobacteria, a solution of sulfuric acid is formed that dissolves the surface soils to create pools and cones of clay and mud. Along with hydrogen sulfide, steam, carbon dioxide, and other gases explode through the layers of mud.

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
The Hverir geothermal area, at the foot of Namafjall mountain at Namaskard pass in the Krafla volcanic fissure system, is a barren field of gurgling sulfur cauldrons, hot springs, fumaroles (steam vents) including a prominent one that gives off a loud hissing of steam and gases, solfataras (fumaroles that give off only sulfurous gases), and boiling mud pots. The hot springs produce considerable sulfur deposits, which in past centuries were mined to produce gunpowder.
It is a fumarole on the side of the Katanuma lake.
After the volcanic eruption, this lake was formed.

A large fumarole in the size of a hill at Monument Geyser Basin. I never noticed that formation to the right before. I had a good time investigating it. It is nice to know that even though you have been to a place many times, something new can catch your eye.

White Island is known for its unique geothermal activity and its high concentration of sulfur. The island is home to several active vents that release gases, including sulfur dioxide, hydrogen sulfide, and carbon dioxide.
The sulfur on the island is primarily in the form of sulfurous acid and sulfuric acid, which creates a distinctive acidic environment. This acidic environment supports the growth of sulfur-loving microorganisms, which give the island its bright yellow coloration in some areas.
Sulfur mining was conducted on the island in the late 19th and early 20th centuries, with the sulfur being used in the production of fertilizers, gunpowder, and other industrial products. However, mining was discontinued due to the difficult conditions and the risks associated with working on an active volcano.
Today, the sulfur on the island is mainly of interest to geologists and researchers studying volcanic activity and geothermal systems. Visitors to the island can observe the sulfur vents and the distinctive yellow coloration in some areas, but access to these areas is restricted due to safety concerns associated with the island's active volcanic activity.

This was an awesome and colorful fumarole (dead). I wish I'd taken more photos of it and those around it. There were so many colors like broken pottery everywhere: solid ochres, bright dandelion yellows, rust reds, orangey-oranges, chalky whites, and pale pinks.
Nestled along the Reykjanes Peninsula, Krýsuvík is a striking geothermal field where the Earth hisses, bubbles, and steams. Surrounded by colorful rhyolite hills, the area features boiling mud pots, steaming fumaroles, and sulfur-stained terrain. It's part of the Mid-Atlantic Ridge, where tectonic plates drift apart. Wooden boardwalks allow visitors to walk safely through this active landscape. The area is also home to nearby Kleifarvatn Lake
Seltún is a vibrant geothermal field located within the Krýsuvík . Known for its boiling mud pools, steaming fumaroles, and vividly colored earth, the site showcases intense geothermal activity just beneath the surface. Wooden boardwalks wind through the field, allowing safe exploration of this otherworldly landscape. The rich mineral deposits stain the ground in hues of red, yellow, green, and white, creating a dramatic visual display and making it a popular stop for photographers, geologists, and curious travelers.
