Upper Geyser Basin, Yellowstone National Park, Wyoming, USA.
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.

Norris Geyser Basin is the hottest and most changeable thermal area in Yellowstone Park. Ledge Geyser, fumaroles, created from hi heat and low-water, create the hottest of Yellowstone's thermal features.
Akademia Nauk (also known as Karymsky Lake) is a lake filled caldera of a dormant volcano. It's in close proximity (1-2h walk) of Karymsky volcano.

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.
Valley of Geysers is the only geyser field in Eurasia and has the second highest concentration of geysers in the world. Visitors (for their safety) have to stick to walking on board walks to the points of interest. The Geysernaya river runs through it, slopes from which are covered with fumaroles.
Uzon caldera (9 x 12km) was formed about 40000 years ago following a series of eruptions of a volcano. It is now a stunning landscape (particularly against the back drop of Autumn colours) dotted with geothermal activity (hot springs, mud pots, fumaroles etc).
Krýsuvík is situated on the Reykjanes peninsula in Iceland. It is in the south of Reykjanes in the middle of the fissure zone on the Mid-Atlantic Ridge which traverses Iceland. Krýsuvík consists of several geothermal fields. In this area exist a lot of solfataras, fumaroles, mud pots and hot springs.

Red Spouter, a fumarole that looks like tomato soup with some cinnamon in it, is an interesting feature that didn't exist before 1959, when a large earthquake at Hebgen Lake, many miles to the west, shook up much of Yellowstone's underground "plumbing."
I haven't found documentation to this effect, but I guess the color is due to iron content.

Hot springs are sites where groundwater emerges at the Earth’s surface (or on the seafloor). Hot spring water has to be higher in temperature than the human body (an admittedly arbitrary definition): over 98° Fahrenheit or over 37° Celsius. Geysers are hot springs that episodically erupt columns of water. The highest concentration of geysers and hot springs anywhere is at the Yellowstone Hotspot Volcano in northwestern Wyoming, USA.
Beryl Spring is located in Gibbon Canyon in Yellowstone’s Gibbon Geyser Basin. It has hot, aquamarine-colored water, hence the name “Beryl” (aquamarine is a bluish, gem-quality variety of the mineral beryl, Be3Al2Si6O18 - beryllium aluminosilicate). The pool has constant, energetic roiling and boiling, accompanied by significant overflow in a well-developed runoff channel. Behind Beryl Spring is a prominent, noisy fumarole that has been given the catalog designation GGCGNN073. Fumaroles are hot steam vents.

It's even louder than it sounds in real life, like an aeroplane taking off.
Yes, someone is attempting to roast root vegetables in there, or possibly bake bread.

Fumarole auf Vulcano. Extrem heiße Sublination von Kristellen aus Schwefeldämpfen. In den roten Bereichen beginnen die Kristalle wieder zu schmelzen. Kleine Tröpfchen oberhalb und 2 große Tropfen rechts Mitte neben der Austrittsöffnung. Die Nahaufnahmen waren wegen der heißen und giftigen Gase im gesamten Fumarolenfeld an diesem Tage recht schwierig unf gefährlich.
What we saw were probably fumaroles spewing some steam. I do remember the smell of sulfur.
There had been rumblings in this area for the past couple of weeks.

Occasionally the wind would pick up and the steam from the fumarole would blow across the boardwalk. You probably need to be careful around here when the wind picks up.
