Crater Lake - Oregon

Crater Lake is a caldera lake in the western United States, located in south-central Oregon. It is the main feature of Crater Lake National Park and is famous for its deep blue color and water clarity. The lake partly fills a nearly 2,148-foot (655 m)-deep caldera[1] that was formed around 7,700 (± 150) years ago[2] by the collapse of the volcano Mount Mazama. There are no rivers flowing into or out of the lake; the evaporation is compensated for by rain and snowfall at a rate such that the total amount of water is replaced every 250 years. At 1,943 feet (592 m), the lake is the deepest in the United States, and the seventh[3] or ninth deepest in the world, depending on whether average or maximum depth is measured. Crater Lake is also known for the "Old Man of the Lake", a full-sized tree which is now a stump that has been bobbing vertically in the lake for over a century. The low temperature of the water has slowed the decomposition of the wood, hence the longevity of the bobbing tree. Two islands are in Crater Lake; Wizard Island formed from a cinder cone that erupted after Crater Lake began to fill with water, and the smaller Phantom Ship has seven different trees living on it. There are also colonies of violet green swallows and several varieties of wildflowers and lichens living there. While having no indigenous fish population, the lake was stocked from 1888 to 1941 with a variety of fish. Several species have formed self-sustaining populations

Mount St. Helens - Washington State

Mount St. Helens (known as Lawetlat'la to the indigenous Cowlitz people, and Loowit to the Klickitat) is an active stratovolcano located in Skamania County, Washington, in the Pacific Northwest region of the United States. It is 96 miles (154 km) south of Seattle, Washington, and 50 miles (80 km) northeast of Portland, Oregon. Mount St. Helens takes its English name from the British diplomat Lord St Helens, a friend of explorer George Vancouver who made a survey of the area in the late 18th century. The volcano is located in the Cascade Range and is part of the Cascade Volcanic Arc, a segment of the Pacific Ring of Fire that includes over 160 active volcanoes. This volcano is well known for its ash explosions and pyroclastic flows. Mount St. Helens is most notorious for its catastrophic eruption on May 18, 1980, at 8:32 a.m. PDT, the deadliest and most economically destructive volcanic event in the history of the United States. Fifty-seven people were killed; 250 homes, 47 bridges, 15 miles (24 km) of railways, and 185 miles (298 km) of highway were destroyed. A massive debris avalanche triggered by an earthquake measuring 5.1 on the Richter scale caused an eruption that reduced the elevation of the mountain's summit from 9,677 ft (2,950 m) to 8,365 ft (2,550 m), replacing it with a 1 mile (1.6 km) wide horseshoe-shaped crater. The debris avalanche was up to 0.7 cubic miles (2.9 km3) in volume. The Mount St. Helens National Volcanic Monument was created to preserve the volcano and allow for its aftermath to be scientifically studied. As with most other volcanoes in the Cascade Range, Mount St. Helens is a large eruptive cone consisting of lava rock interlayered with ash, pumice, and other deposits. The mountain includes layers of basalt and andesite through which several domes of dacite lava have erupted. The largest of the dacite domes formed the previous summit, and off its northern flank sat the smaller Goat Rocks dome. Both were destroyed in the 1980 eruption.

Geysers - Sonoma County California

The Geysers are located in Sonoma, the wine country, and has many fantastic spas where one can soak in the hot lava sands, enjoy a massage and have a glass of wine or even hard liquor. For about 12,000 years, Indians built steambaths at the Geysers and used the steam and hot water for healing purposes and cooking. When Euro/Americans first entered the area, six Indian tribes inhabited the area around the Geysers, three bands of Pomo people, two bands of Wappo people, and the Lake Miwok people. According to Stephen Powers in 1871, "Wappo invalids were accustomed to wallow in the hot, steaming mud and pools, receiving benefit therefrom into their bodies." The Wappo also collected sulphur which they called te'ke and a Wappo village, named tekena'ntsonoma (teke sulphur + nan well containing water + tso ground + no'ma village) was located about 12 miles (19 km) southeast of Cloverdale and on the present-day Sulphur Creek. The Geysers were first seen by Euro/Americans and named in 1847 during John Fremont's survey of the Sierra Mountains and the Great Basin by William Bell Elliot who called the area "The Geysers," although the geothermal features he discovered were not technically geysers, but fumaroles. Between 1848 and 1854, The Geysers was developed into a spa named The Geysers Resort Hotel , which attracted tourists including Ulysses S. Grant, Theodore Roosevelt and Mark Twain The Geysers, comprising 45 square miles along the Sonoma and Lake County border and it is the largest complex of geothermal power plants in the world. Geothermal power is energy derived from the heat of the earth's core. "Geo" means "from the earth" and "thermal" means "heat." This type of energy is clean and predictable, offering a reliable and renewable energy source. In the Mayacamas Mountains, located north of San Francisco, naturally occurring steam field reservoirs below the earth's surface are being harnessed by Calpine to make clean, green, renewable energy for homes and businesses across Northern California. The Geysers meets the typical power needs of Sonoma, Lake and Mendocino counties, as well a portion of the power needs of Marin and Napa counties. In fact, The Geysers satisfies nearly 60 percent of the average electricity demand in the North Coast region from the Golden Gate Bridge to the Oregon border. The Geysers is one of the most reliable energy sources in California, delivering extremely high availability and on-line performance, and accounts for one-fifth of the green power produced in California.

Kilauea volcano - Hawaii

Located 30 miles southwest of Hilo, this is the home of Kilauea volcano, one of the most active volcanoes on earth. The chance to witness the primal process of creation and destruction make this park one of the most popular visitor attraction in Hawaii and a sacred place for Native Hawaiians. Founded in 1916, the Park encompasses 333,000 acres from the summit of Maunaloa to the sea. Here you'll find 150 miles of hiking trails through volcanic craters, scalded deserts and rainforests as well as a museum, petroglyphs, a walk-in lava tube and two active volcanoes: Maunaloa, which last erupted in 1984 and Kilauea which has been erupting since January 3rd, 1983. Kilauea is sometimes called "the world's only drive-in volcano." This prolific volcano currently produces 250,000-650,000 cubic yards of lava per day, enough to resurface a 20-mile-long, two-lane road daily. Pele, the volcano goddess who lives here, is very unpredictable.

Gellért Thermal Baths - Buda Hungary

Part of the famous Hotel Gellért in Buda, the Gellért Thermal Baths and Swimming Pool (also known as the Gellért Baths or in Hungarian as the Gellért fürdo) is a bath complex in Budapest, Hungary References to healing waters in this location are found from as early as the 13th century. A hospital was located on this site during the Middle Ages. During the reign of the Ottoman Empire , baths were also built on this particular site. The "magical healing spring" used the Turkish during the 16th and 17th centuries. The bath was called Sárosfürdo ("muddy” bath), because the mineral mud settled at the bottom of pools. The bath complex was built between 1912 and 1918 in the (Secession) Art Nouveau style. It was damaged during World War II, but then rebuilt. The Gellért Baths complex includes thermal baths, which are small pools containing water from Gellért hill's mineral hot springs. The water contains calcium, magnesium, hydrocarbonate, alkalis, chloride, sulfate and fluoride. Medical indications of the water includes degenerative joint illnesses, spine problems, chronic and sub-acute joint inflammations, vertebral disk problems, neuralgia, vasoconstriction and circulatory disturbances; inhalation problems for the treatment of asthma and chronic bronchitis problems.[1] The temperature of the water is between 35 °C and 40 °C.The thermal baths are decorated beautifully with mosaic tiles. Gellért Spa is famous for its main hall with gallery and glass roof, built in Art-Nouveau style.

Volcán Atitlán - Guatemala

Volcán Atitlán (Spanish pronunciation: [ati'tlan]) is a large, conical, active stratovolcano adjacent to the caldera of Lake Atitlán in the Highlands of Guatemala. The volcano has been quite active historically, with more than a dozen eruptions recorded between 1469 and 1853, the date of its most recent eruption. Atitlán is part of the Central American Volcanic Arc. The arc is a chain of volcanoes stretching along Central America formed by subduction of the Cocos Plate underneath the Caribbean Plate. These volcanoes are part of the Ring of Fire around the Pacific Ocean. Volcán Atitlán is few miles south of Volcán Tolimán, which rises from the southern shore of Lake Atitlán. Volcán San Pedro rises above Lake Atitlán northwest of Volcán Atitlán. A long narrow bay separates Volcán Atitlán and Volcán Toliman from Volcán San Pedro.

Pamukkale Terraces - Turkey

Pamukkale's terraces are made of travertine, a sedimentary rock deposited by water from the hot springs. In this area, there are 17 hot water springs in which the temperature ranges from 35 °C (95 °F) to 100 °C (212 °F).[citation needed] The water that emerges from the spring is transported 320 metres (1,050 ft) to the head of the travertine terraces and deposits calcium carbonate on a section 60 to 70 metres (200 to 230 ft) long covering an expanse of 24 metres (79 ft) to 30 metres (98 ft). When the water, supersaturated with calcium carbonate, reaches the surface, carbon dioxide de-gasses from it, and calcium carbonate is deposited. The depositing continues until the carbon dioxide in the water balances the carbon dioxide in the air. Calcium carbonate is deposited by the water as a soft jelly, but this eventually hardens into travertine. This reaction is affected by the weather conditions, ambient temperature, and the flow duration. Precipitation continues until the carbon dioxide in the thermal water reaches equilibrium with the carbon dioxide in the atmosphere. Measurements made at the source of the springs find atmospheric levels of 725 mg/l carbon dioxide, by the time this water flows across the travertines, this figure falls to 145 mg/l. Likewise calcium carbonate falls from 1200 mg/l to 400 mg/l and calcium 576.8 mg/l to 376.6 mg/l. From these results it is calculated that 499.9 mg of CaCO3 is deposited on the travertine for every liter of water. This means that for a flow rate of 1 i/s of water 43191 grams are deposited daily. The average density of a travertine is 1.48 g/cm3 implying a deposit of 29.2 dm3. Given that the average flow of the water is 465.2 l/s this implies that it can whiten 13,584 square metres (146,220 sq ft) a day, but in practice this area coverage is difficult to attain. These theoretical calculations indicate that up to 4.9 square kilometres (1.9 sq mi) it can be covered with a white deposit of 1 millimetre (0.039 in) thickness.

Arenal Volcano - Costa Rico

Arenal Volcano National Park is a Costa Rican national park in the central part of the country, forming the Arenal Tilaran Conservation Area. The park encompasses the Arenal Volcano, which "was" the most active in the country, which had previously been believed to be dormant until a major eruption in 1968. It neighbors Lake Arenal, which is the site of the country's largest hydroelectricity project, the Lake Arenal Dam. The park also contains a second volcano, Chato, whose crater contains a lagoon. It is also called Cerro Chato (literally Mount Chato) as it has been inactive for around 3500 years–coinciding with the creation and growth of Arenal itself. In and around the park are various lodges and hotels, some with their own hot springs, and others focused on the wildlife of the area. Within the national park are the Museum of Vulcanicity and a ranger station.

Masaya Volcano - Nicaragua

Masaya is a caldera located in the department of Masaya, 20 km south of Managua, Nicaragua. It is Nicaragua's first and largest National Park, and one of 78 protected areas of Nicaragua. The complex volcano is composed of a nested set of calderas and craters, the largest of which is Las Sierras shield volcano and caldera. Within this caldera lies a sub-vent, which is Masaya Volcano sensu stricto. The vent is a shield type composing of basaltic lavas and tephras and includes a summit crater. This hosts Masaya caldera, formed 2500 years ago by an 8-km³ basaltic ignimbrite eruption. Inside this caldera a new basaltic complex has grown from eruptions mainly on a semi-circular set of vents that include the Masaya and Nindiri cones. The latter host the pit craters of Masaya, Santiago, Nindiri and San Pedro. Observations in the walls of the pit craters indicate that there have been several episodes of cone and pit crater formation.

Yellowstone Caldera - Wyoming

Yellowstone, widely held to be the first national park in the world , is known for its wildlife and its many geothermal features, especially Old Faithful Geyser, one of the most popular features in the park. It has many types of ecosystems, but the subalpine forest is most abundant. It is part of the South Central Rockies forests ecoregion. Yellowstone National Park spans an area of 3,468.4 square miles (8,983 km2), comprising lakes, canyons, rivers and mountain ranges. Yellowstone Lake is one of the largest high-altitude lakes in North America and is centered over the Yellowstone Caldera, the largest supervolcano on the continent. The caldera is considered an active volcano. It has erupted with tremendous force several times in the last two million years. Half of the world's geothermal features are in Yellowstone, fueled by this ongoing volcanism. Lava flows and rocks from volcanic eruptions cover most of the land area of Yellowstone. The park is the centerpiece of the Greater Yellowstone Ecosystem, the largest remaining nearly-intact ecosystem in the Earth's northern temperate zone.

Wai-o-Tapu Thermals - New Zealand

Waiotapu , (Maori for "sacred waters") is an active geothermal area at the southern end of the Okataina Volcanic Centre, just north of the Reporoa caldera, in New Zealand's Taupo Volcanic Zone. It is 27 kilometres south of Rotorua. The area has many hot springs noted for their colourful appearance, in addition to the Lady Knox Geyser, Champagne Pool, Artist's Palette, Primrose Terrace and boiling mud pools. The geothermal area covers 18 square kilometres. Prior to European occupation the area was the homeland of the Ngati Whaoa tribe who descended from those on the Arawa waka (canoe). The area has a long history as a tourist attraction. While the area has been protected as a scenic reserve since 1931, a tourist operation occupies part of the reserve under a concession. It operates under the name "Wai-O-Tapu Thermal Wonderland". The business was bought in 2012 by Te Arawa Group Holdings, a local Maori tribal business, from the Sewell/Leinhardt family, who had run it for 30 years.
