Geysers & Hot Springs

Extractions: Weather Is there any better reward, after a long hiking day, than to relax in a pool of hot water, softening the muscles and enjoying spectacular panorama ? What if the conscience tells you, you deserve it ? Hot springs and pools have been used for hygienic purposes, but man can also enjoy by looking and listening, even smelling. Since the colonisation of Iceland, bathing in pools has been a tradition, often in a social and political context (naked man is without arms), rather than hygienic. Maybe not surprising, since many natural pools are not very "clean". Sand and algae may stick to the body, specially when bathing with garments on (any serious bathtaker does so naked, when possible). Still today there are too many people which can´t see warm water without starting to dig, make dams or rolling stones. Therefore we don´t dare describing particular pools or geothermal zones, except for the most known. We´ll try to treat the subject generally; mostly what to avoid, how to behave when in geothermal zones, along with tips and tricks on how to use the presence of natural geothermal sources when hiking and camping. Many of the best known natural pools are made by local farmers, which have been gathering their sheep in the area. Some are simple dams but some are neatly constructed of stone, near the source(s).

Extractions: It is likely, however, that most of the medicinal effects of spa therapy result from the environmental factors of the location and facilities of the spa. The beautiful town of Bath has the only thermal springs in England, which usually yield more than 500,000 gallons daily at a temperature of 120º F (49º C). The waters are drunk medicinally and used for hydrotherapy treatments, and the Georgian Pump Room, with its fountain, has long been a rendezvous for visitors who are "taking the waters." Many European spas are located in forested alpine settings such as Sankt Moritz, Switz., Évian-les-Bains, Fr., Badgastein, Austria, and Bormio, Italy. Japan has several thousand hot springs, many of which have been converted into spas or public baths.

Extractions: Calistoga and mud go way back - Mud baths said to relax muscles, sooth aches, improve circulation and smooth the skin have been a visitor staple in Calistoga ever since Sam Brannan reined in the thermal springs at the foot of Mount St. Helena and opened his Calistoga Hot Springs Resort in the 1860s. Spa after spa followed; today there are more than a dozen, making Calistoga the most spa-ified town in the West. "In the natural state, what we had around here was hot springs bubbling up all around. When they put wells down for swimming pools, it concentrated it, and the hot springs were lost," said John Merchant, whose Indian Springs Spa and Resort stands on the site of Brannan's fashionable 19th century watering hole.

http://www.frommers.com/destinations/yellowstonenationalpark/0809027239.html

Extractions: Here's a way to identify the four most common types of thermal attractions in Yellowstone. Geysers, Hot springs are closely related to geysers but don't display the same eruptions because they don't develop the same subsurface pressures. Their colorful appearance is a result of different minerals, algae, the absorption of light by colloidal particlestiny, suspended particles of liquidand reflections. Mud pots are hot springs on the Earth's surface that are formed as heated water mixes with clay and congealed minerals. Some mud pots are very colorful; others are unsightly and smelly. Fumaroles are steam vents known as "dry geysers," from which gases rush into the air; they are considered hot springs that lack a liquid component.

Extractions: Visitor Info Public Holidays Transport Guide to NZ Road Rules ... History New Zealand lies in the Southern Pacific Ocean, 1600km east of Australia. It is made up of the North and South Islands and a number of smaller islands, with a total land area of 266,200sg km. Mountain ranges and hill country dominate New Zealand's landscape; one of the most striking physical features is the Southern Alps. These, along with fiords, glaciers and lakes, and the coastal plains of Canterbury and Southland, add to the variety of the South Island scenery. In the North Island, the volcanic interior contains New Zealand's largest lake, Lake Taupo, and most of the country's active volcanoes - Ruapehu, Ngauruhoe and Tongariro - all usually quiet, although Ruapehu has been active since September 1995. Hot springs, geysers and mud pools also form part of the volcanic system centred around Rotorua. Population

http://www.nps.gov/yell/nature/geothermal/hotsprng.htm

Extractions: Norris Geyser Basin F. The highly energized water is less dense than the colder, heavier water sinking around it. This creates convection currents that allow the lighter, more buoyant, superheated water to begin its slow, arduous journey back toward the surface through rhyolitic lava flows, following the cracks, fissures, and weak areas of the earth’s crust. Rhyolite is essential to geysers because it contains an abundance of silica, the mineral from which glass is made. As the hot water travels through this "natural plumbing system," the high temperatures dissolve some of the silica in the rhyolite, yielding a solution of silica within the water. At the surface, these silica-laden waters form a rock called geyserite, or sinter, creating the massive geyser cones; the scalloped edges of hot springs; and the expansive, light- colored, barren landscape characteristic of geyser basins. While in solution underground, some of this silica deposits as geyserite on the walls of the plumbing system forming a pressure-tight seal, locking in the hot water and creating a system that can withstand the great pressure needed to produce a geyser.

Yellowstone Geothermal Resources
Nowhere else in the world can we find the array or number of geysers,hot springs, mud pots, and fumaroles found in Yellowstone.
http://www.nps.gov/yell/nature/geothermal/ycr/

Extractions: The park's thermal features lie in the only essentially undisturbed geyser basins left worldwide. In Iceland and New Zealand, geothermal drill holes and wells 2.5 - 6.2 miles distant have reduced geyser activity and hot spring discharge. Despite the proximity of roads and trails in the largest basins, few park features have ever been diverted for human use (such as bathing pools or energy). YNP offers visitors and scientists an opportunity to appreciate thermal features in their natural, changing state. For example, research on thermophilic bacteria, algae mats, predators, and their environments is applied elsewhere to energy fuel production and extraction, bio-mining, control and removal of toxic wastes, development of new surfactants and fermentation processes, and other fields. Park features have always been subject to some influence from human vandalism. In the park's early years it was common for visitors to use thermal features as "wishing wells", and this practice continues to some degree today. Coins, rocks, trash, logs or stumps, and other paraphernalia are found in the narrow vents of geysers and hot springs. Features have been plugged up, and little can be done to repair the damage. Radical attempts to siphon surface water and induce eruptions have occasionally been tried on famous features such as Morning Glory Pool, with varying degrees of success. Damage also occurs when people leave walkways and climb on features, or occasionally break pieces of sinter or travertine off for souvenirs (Marler 1973).

Extractions: World Geography United States Geography Geysers are natural hot springs that intermittently eject a column of water and steam into the air. They exist in many parts of the volcanic regions of the world such as Japan and South America but their greatest development is in Iceland, New Zealand, and Yellowstone National Park. There are 120 named geysers in Yellowstone National Park, Wyoming, and perhaps half that number unnamed. Most of the geysers and the 4,000 or more hot springs are located in the western portion of the park. The most important are the following: Norris Geyser Basin has 24 or more active geysers; the number varies. There are scores of steam vents and hot springs.

Fire Interpretation These erupting hot springs are a fluke of nature, occurring only in a handful of locations. Yellowstone National Park, in Wyoming, has more geysers than all the other geyser locations in the world combined. Geysers are such remarkable feats of nature, and come in a wide variety of descriptions. Some erupt fairly regularly and most eruptions are pretty similar to others in appearance and height. Some constantly erupt, and others erupt almost all the time. Most are fairly erratic about the timing of their eruptions, and quite a few have wide variations in the nature of their eruptions. A number of geysers are connected to other geysers underground and their eruption timing and scale is connected. Some geysers erupt from within a hot spring or pool. Others have developed deposits of geyserite into cones around their orifice. These deposits can be simple mounds or elaborate deposits that deflect and shape the eruption itself. Some geysers have developed such extensive cones that they have choked themselves off and no longer erupt.

Fire Interpretation Yellowstone is filled with thermal features - maybe 10,000 in all. For every splashing geyser there are many beautiful and fascinating hot springs and pools. Many Yellowstone hot springs are shaped like the inside of a morning glory flower, with deep blue to purple tones over the deep center of the pool transitioning to lighter blues, aquas, and then yellow or rust colors on the shallower outer rims. There is an endless variety of edge shapes with some edges gradually thinning to gravel or algae mats and others having steep sides with cockled edges. Morning Glory Pool, in the Upper Geyser Basin, has long been famous for its colors and the fascinating shape of its pool, but the pool has suffered greatly from the objects visitors have thrown in Some springs and pools run constantly, while others rise and fall in tune with nearby springs and geysers. Grand Prismatic Spring, in the Midway Geyser Basin has an outflow of over 500 gallons per minute. Most of the Firehole River is filled with outflows from hot springs and geysers.
