A couple take a break and look the strange landscape of iceland. Landmannalaugar - Thorsmork trail, Iceland.
Tigger as a Formosan mountain dog mix is very independent and not generally thrilled at being picked up. After an awkward moment posed in front of a fumarole, she was off.
Námafjall high temperature geothermal area, North Iceland.
The area is characterized by fumaroles, hot grounds and mudpots. At a depth of 1000m, temperature is > 200◦C. Along with the steam, comes fumarole gas like hydrogen sulphide (H2S), which is responsible for the characteristic hotspring smell in this area. The hot springs produce considerable sulphur deposits, which are formed when the fumarole gas mixes with air. Besides the sulphur deposits, a mixture of silica and gypsum forms around the fumaroles. In previous centuries, sulphur was mined here to produce gun powder and for use in church (Courtesy of signpost at the geothermal field)

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.
White Island (Whakāri), 48km offshore from NZ, is the northernmost active volcano in the Taupo Volcanic Zone - a 250km-long zone of intense volcanism that marks the boundary of the Australian and Pacific tectonic plates.
The island has been built up by continuous volcanic activity over the past 150,000 years. About 70 percent of the volcano is under the sea, making this massive volcanic structure the largest in New Zealand.
A sulphur mining venture began on the island in 1885; this was stopped abruptly in 1914 when part of the crater wall collapsed and a landslide destroyed the sulphur mine and miners' village; twelve lives were lost.
The most recent eruption occured in 2000. A new vent developed and began to emit ash. An eruption occurred late in July which covered the crater area in scoria, also displacing the main crater lake and forming a new explosion crater 150 m across.

Hverir is a very active geothermal area next to Námafjall mountain close to Lake Mývatn in northeast Iceland. The air in this area smells sulphurous and at times can be quite pungent.
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.

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.
