The Pinnacles - These towering needle-like formations of rock, called fossil fumaroles, projecting from the Sand Creek Canyon floor, were formed under sheets of volcanic pumice that preceded Mazama's collapse. As the surface of the hot pumice cooled over the years, steam and gases were released by the hot rocks underneath through vents and tubes that were welded into cement hardness by their passage. These ancient vents now stand alone due to the erosion of the surrounding softer materials.
I noticed this effect in Rotorua, New Zealand. Wood near fumaroles and geothermal vents turns this lovely blue-black color. The crossbeams were coated with a resin that seems to have protected them.
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
KrĂ˝suvĂk 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. KrĂ˝suvĂk consists of several geothermal fields. In this area exist a lot of solfataras, fumaroles, mud pots and hot springs.
Das geothermale Gebiet KrĂ˝suvĂk liegt im SĂĽden der Reykjanes-Halbinsel in Island in der Mitte des Spalte des Mittelatlantischen RĂĽckens der quer durch Island fĂĽhrt. In diesem Gebit gibt es Schwefelquellen, Fumarolen, Schlammtöpfe und heiĂźe Quellen.
Namafjall is a high-temperature geothermal area with fumaroles and mud pots. At a depth of 1000m, the temperature is above 200 degrees Celcius. Along with the steam comes fumarole gas, such as hydrogen sulfide which is responsible for the characteristic hot spring smell in these areas. The hot spring produce considerable sulphur deposits. In previous centuries sulphur was mined in Iceland to produce gun powder.
CAUTION: Unsafe soil and high temperatures (80-100C). Please walk only on the paths and marked trails.

La zona de Myvatn és on hem vist més fumaroles. És molt curiós veure com hi ha forats a terra on una aigua amb color de ciment bull com si estigués dintre d'una olla. La pudor a sofre és força intensa i desagradable. Els colors ataronjats són deguts al sofre que hi ha arreu, inclòs l'aire.
La foto Ă©s una panorĂ mica muntada amb el programa Hugin a partir de 10 fotos verticals.

Myvatn area is where we have seen more fumaroles. it is curious to see how there are holes in the land with colored water like boiling cement into a pot. The sulfur stink is quite intense and unpleasant at the end. The orange color is due to the sulfur around, also in the air. The photo is a panoramic one composed from ten individual vertical photos joined with Hugin.
Photos are taken with a nikon d700 and an objective micro nikkor 60.
Recent trips to Mount St. Helens (and a thorough examination of all my photos) seems to show a new vent on the upper west crater wall. It was venting quite vociferously yesterday afternoon!
This is a reminder that Mount Saint Catherine in Grenada is a volcano! This is on one of the slopes of Mount Saint Catherine on the island of Grenada in the Caribbean Sea.
Crayfish in Fumarole Bay. There are indian stories about giant crayfish that guarded the lake in the past. The park service, however, believes that crayfish are not native to the lake. They believe the crayfish were introduced by William Steele himself, in order to attract visitors to the lake

The fumarole field at Asahidake, an area of thermal springs and gas vents where magma or hot igneous rocks at shallow depth are releasing gases or interacting with groundwater.
Asahidake, a stratovolcano, is the tallest mountain in HokkaidĹŤ, Japan. Part of the Daisetsuzan Volcanic Group of the Ishikari Mountains, it is located in the northern part of the Daisetsuzan National Park.

Nps.gov: Along Fountain Paint Pot Trail you will see various hydrothermal features that are expressions of Yellowstone’s still active volcano. Within this geologic system, each type of thermal feature is represented. They can be grouped into two general categories—those with a great deal of water (hot springs and geysers) and those with limited water (mudpots and fumaroles). Despite their structural similarities, no two features are exactly alike:
Silex Spring, Fountain Paint Pot, Red Spouter, Fumaroles, Twig Geyser, Fountain Geyser, Morning Geyser, Jet Geyser, Spasm Geyser, Clepsydra Geyser, Jelly Geyser.
Notes: Thermal activity throughout this entire area. Stay on the boardwalk at all times.

Mud Volcano Trail The thermal features at Mud Volcano and Sulphur Caldron are primarily mud pots and fumaroles because the area is situated on a perched 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 and is oxidized to sulfuric acid by microbial activity, which 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.
A series of shallow earthquakes associated with the volcanic activity in Yellowstone struck this area in 1978. Soil temperatures increased to nearly 200 °F (93 °C). The slope between Sizzling Basin and Mud Geyser, once covered with green grass and tree]s, became a barren landscape of fallen trees known as "the cooking hillside".
