El Tatio Geysers and Hot Springs
Geologic Summary
Tucle horst (tectonically raised block of crustal material) on the west and a chain of Pliocene-Quaternary aged volcanoes to the east . The Tatio graben is filled with volcanic material up to 1,800 meters thick. The main reservior of water is found within the permiable layers of volcanic materials. These permiable volcanic layers are capped by impermiable volcanic material. A series of fractures allow the hot water to reach the surface. The heat source is not known for certain, but may be the result of the cooling of the volcanic materials that were deposited in the graben, or a body of magma beneath the graben which is cooling. The thermal activity at El Tatio covers and area of approximately 10 square kilometers and occurs in the form of geysers steaming pools boiling pools fumeroles ... pools where the water is "bubbling" or boiling . In the case of the geysers, the force of the boiling water, within a restricted conduit, results in the water being propelled above the surface. At the time of the author's visit, only one geyser was active , shooting water approximately 2 meters above the surface. Information from local guides indicate that activity has varied over time and that more geysers have been active in the past. Many of the pools and hot springs have

The Top Three - Geyser Areas In my opinion the three "must-sees", in their order of importance, are The Upper Geyser Basin (home to Old Faithful Geyser), The Grand Canyon of the Yellowstone and The Fountain Paint Pot Trail. These areas are described below: 1. OLD FAITHFUL and the UPPER GEYSER BASIN: Of course, everyone goes to see Old Faithful but few walk even the short distance needed to cross the river and see Geyser Hill and even less spend time in the rest of the geyser basin. Please plan to spend some time in this area - there is a lot more to see than just Old Faithful! This one square mile basin is home to hundreds of geysers and some very pretty hot springs. Take your time and explore. Sit, relax and watch some of the geysers. Only by taking your time can you experience Yellowstone's unique thermal wonders. An interpretive pamphlet about the Upper Geyser Basin is available at the visitor center and at the start of the boardwalk behind Old Faithful. Pamphlets cost $0.25 (1995) but may be borrowed and returned at the trail head at no charge. Besides describing some of the basins features the pamphlet also includes a map of the basin which shows the boardwalks and the locations of some of the major geysers and hot springs.

Colorful Yellowstone
Grand Prismatic Spring (Russ Finley)
Although Yellowstone is famous for its geysers, the beautiful colors associated with the geysers and hot springs are often a surprise. One sees hot water flowing over patches of brilliant yellow, orange, red, and green; hot pools lined with color; of even steam which appears to be colored.
The early trappers and explorers noted the colors, as did the geologists who mapped the thermal basins in the 1870s. In fact, it was a geologist, Walter H. Weed, who in 1889 first recognized that the colorful deposits of Yellowstone hot springs were microbial.
The presence of living creatures in water too hot to touch is really amazing. But even more impressive is the fact that the organisms of hot springs are not only living, but thriving. In fact, they are so perfectly adapted to these hot environments that they can live no where else.
Such organisms, called thermophiles, are found in hot environments all over the world - not only in hot springs but also in volcanoes, deserts, and artificial thermal environments such as power plants and hot water heaters But nowhere else in the world are they so obvious, and in such brilliant profusion, as in Yellowstone.

Norris Geyser Basin
Russian
View on Norris Geyser Basin Thermal features of this area are due to a chamber of hot magma beneath the park which was left behind a gigantic explosion somewhere six hundred thousand years ago. This magma heats the water that percolates down from the surface along fractures and faults. The superheated water rises to the surfaces to form either geysers or hot springs. Geysers from if the plumbing channels contain the construction. The superheated water builds up the pressure beneath the construction until it flashes into the steam pushing the cooler water above up and out as geyser erupts. Hot springs form when there is no plumbing construction and superheated water cools down while reaching surface and gets replaced by hot water from deeper sources. Constant circulation prevents eruptions as it is the case with Mammoth Hot Springs "Constant" Geyser Norris Geyser Basin area is the hottest and most dynamic area of the park. (Perhaps, dynamics and changeability are the most distinctive features of any thermally active area since you will hear the same about Mammoth Hot Springs as well as Old Faithful area...) First impression of the area is somewhat extraterrestrial. Right in front of the trees there lays a whitish steaming valley with numerous pools of different colors.

The Yellowstone Volcano Observatory: Monitoring a Restless Volcanic Giant
In 1912, when Thomas Jaggar dug a cellar to house a seismograph on the north rim of Kilauea's caldera, there was only one other volcano observatory on earth, at Vesuvius, in Italy. Today, there are numerous volcano observatories around the world, including four in the United States besides HVO: the Cascades Volcano Observatory in Washington state, the Alaskan Volcano Observatory, the Long Valley Observatory in California, and our newest sister observatory - the Yellowstone Volcano Observatory (YVO). YVO was established in May 2001 in order to improve the study and monitoring of active geologic processes and hazards of the Yellowstone Plateau volcanic field. The observatory is a joint effort of the U.S. Geological Survey, Yellowstone National Park, and the University of Utah. Yellowstone National Park and the surrounding area encompass the largest active magmatic system in North America. Three cataclysmic explosive eruptions over the last two million years ejected huge volumes of lava and ash - up to 2,000 times more material than Mount St. Helens produced in its devastating 1980 eruption. During these catastrophic eruptions, columns of volcanic ash and gas were shot high into the Earth's stratosphere. The volcanic cloud circled the globe, reducing temperatures worldwide. Fine ash falling downwind of the eruptions blanketed much of North America.

Introduction
Welcome to the Rhynie Chert website. During the Summer of 1997, an intensive drilling program was carried out at the Rhynie Chert Site of Special Scientific Interest (SSSI), near the village of Rhynie, Aberdeenshire, Scotland. The Rhynie Chert, discovered back in 1912, is now world-renowned for the exceptionally preserved early land plants and arthropod fossils which it contains. These fossils are often preserved in three-dimensions in the chert which formed as the result of hot-spring activity during the Lower Devonian (396 Million years ago). The Rhynie chert is commonly cited as an example of one of the earliest terrestrial ecosystems yet discovered on Earth. To date, we have established the sequence lying directly above and below the Cherts and the full thickness of this unusual deposit. However, our interests are not restricted to the early land plants. We hope to investigate the hydrothermal alteration and mineralisation associated with the Rhynie Hot Springs, the oldest known example in the World.
Drilling Program
The Drilling program commenced on July 4th 1997 and ended in the last days of August. In total, nine cored boreholes were completed, four of which were sited within the boundaries of the Rhynie Chert SSSI field. The remaining five holes were drilled in a traverse line near Windyfield farm. All four of the SSSI boreholes encountered various thicknesses of chert, the majority of which is plant-bearing. The next stage in this project involves the completion of lithological logs for each of the boreholes, sampling of the cores and possible correlation between chert beds and lenses between different boreholes. Once completed, this should reveal the temporal and geographical extent of this highly unusual deposit. In total, over 650 metres of core were recovered from the site. Supplementary trenching allowed further refinement of our understanding of the relationship of the cherts to the sediments they occur in

Geothermal Energy and Geysers No two geysers behave in exactly the same way . Studying the system of underground passages that supplies any one of them is a technological challenge. Geysers are distinct from other subterranean emissions. For example, while a volcano vents molten matter, solid rock and gases are released. On the other hand, fumaroles emit only gases or gases and water, but they do not spit water into the air as do geysers. During a late stage of volcanic activity, fumaroles occur along fissures or in apparently chaotic clusters or fields above hot spots in the mantle. Fumaroles are also sometimes described by the composition of their gases as, for example, in chlorine fumaroles. Although not violent, fumaroles can be dangerous to humans and livestock if hazardous or toxic fumes are inhaled. Three components must be present for geysers to exist: an abundant supply of water, an intense source of heat, and specialized plumbing. Remote locations or locations legislatively protected from human activity are becoming increasingly important to maintaining geysers. The set of requirements make geysers a rare geological phenomenon. Water is sometimes not available, as in an arid part of the country. Heat may be close to the surface only along a fault line, where a tectonic plate is being subducted, from volcanic activity, or from a hard to explain hot spot. Even if both water and heat are present, the right plumbing is critical.

Historically Romantic Since 1900... Home Chico Articles / Financial Times "State of Bliss" Weekend FT (Financial Times), How to Spend It, March 2000 Reggie Nadelson In Montana last summer, near Chico Hot Springs, I caught a fish. My first fish, a trout. It's a seductive experience this, drifting in a boat under the enormous blue sky, floating your line on the water, and waiting for the hot sun to draw the fish up towards the surface. The Yellowstone River runs undammed, the tall blue mountains come down to the river banks, the river light turns the high prairie gold. Fishing isn't normally my kind of thing, and neither is the outdoors. Montana, though, has an allure unlike any other place. It's not just the scenery, not just the vast ranches folded into the landscape where, hidden from view, the rich and famous live - and there are plenty of them out here. You roll it around your mouth - Montana - and you believe in the myths: the legendary gold strikes of the 19th century; the fabulous mining towns; the libertarian crazies of the 20th; the desperate clashes between the settler and Indian; the cowboys and the epic landscapes and the vast spaces. There are 800,000 people flung out across a state almost the size of France. I'm in thrall to Montana, to Paradise Valley in particular (Paradise by name, paradise by nature), and to Chico Hot Springs (charmed, in the literal sense).

Yellowstone National Park Norris Geyser Basin Norris Geyser Basin Norris Geyser Basin's Back Basin Norris Geyser Basin. Norris Geyser Basin is the worlds most unpredicitable and changing geyser basin, it contains the worlds tallest active geyser (Steamboat Geyser) as well as being the hottest geyser basin in the world. In one scientific drill hole located at Norris Geyser Basin the temperature was recored at 459 F (237 C) only 1,087 feet (326 meters) below the surface. Norris Geyser Basin is the most acidic geyser basins in the world. With some of the geysers having a pH of 3.3 to 3.6 (almost the pH of vinegar) (water has a pH of 7). So this makes Norris Geyser Basin a Geyser Basin one does not want to miss while in Yellowstone.
What to see at Norris Geyser Basin
  • Echinus Geyser - erupts every 35 to 75 minutes and shoots into the ari 40 to 60 feet (12-18 meters) and lasts for 6 to 14 minutes but can last for 60 minutes or longer. The main attraction though is how close you can get to the geyser when it is going off unlike Old Faithful geyser where you are a couple of hundred of feet away at Echinus you are only 20 to 40 feet away if that.
  • Steamboat Geyser - The worlds tallest geyser is located at Norris Geyser Basin. When it goes off it goes off for about 20 minutes in the water phase and then the steam phase lasts more then an hour. It shoots to a hight of over 300 feet high. But there is a problem that the interval is 4 days to 50 years. The last time it went off was in 1991. But then it just went of in May of 2000 and once again there was not a ranger present to see it. More on the story later.

St. Helens None Remember that caldera eruptions are always very large because the loss of a lot of magma from a reservior below the surface causes the surface to collapse leaving the caldera structure What kind of magma was erupted at Yellowstone and how was it produced? There is certainly plenty of evidence that magma and its heat still exist beneath Yellowstone and that future eruptive activity is very possible. This evidence is:
  • High heat flow- We have many measurements worldwide of heat flow coming out of the Earth. This value is high at volcanically active regions and even higher at Yellowstone.
  • Seismic wave velocities- Earthquakes generate seismic waves that travel through the Earth at different speeds depending on the properties of the rock. These waves travel much slower through melted or partially melted rock. Seismic wave velocities of rocks beneath Yellowstone Caldera suggest that magma (melted rock) exists.

    Travelers to the park should contact park headquarters at for road and weather conditions. T he first and still the most popular national park in the United States, Yellowstone sits astride the Continental Divide in northwestern Wyoming, edging over the borders of Montana and Idaho. This is the world's foremost geothermal region, where molten rock rises close to the surface, providing the heat which results in the hundreds of geysers, fumaroles and mudpots which abound in the park.
    It's an area where catastrophic volcanic eruptions brought immense changes to the landscape, including the great caldera (a collapsed volcano) which created Yellowstone Lake about 600,000 years ago. Every year the abundant snowfall melts into the ground and then the water percolates upward, forced back through the ground as steam. Old Faithful the world's most beloved geyser is the prime example of this geothermal action.

    Despite having lived in Montana for four years and having visited so frequently, I have only visited twice. The first time was around 1990, while I was still in high school. Since I entered the park from West Yellowstone and first visited the Old Faithful area, my impression of the place then was that it smelled of sulfur. I did see quite a variety of animals on that trip, and I did enjoy some of the sights within the park. The other time I visited was in late December 2000. My fiancee and I drove around the northern section of the park, which was the only part accessible to cars during the winter. We did see a large number of elk, although we could not find many other animals. The terraces at Mammoth Hot Springs were buried in snow, so we could not see as much of the geological beauty of the springs, but watching the steam rise from them as well as Yellowstone River was mystifying. Yellostone National Park is one of the best known parks in the world. Droves of tourists visit every year to see the numerous geysers and the plentiful wildlife. The geysers and hot springs are heated by a hot spot underneath the Earth's crust formed by convection directly from the Earth's core. Aside from producing geyser activity, the hot spot sometimes generates earthquakes and produced massive volcanic activity in the past. The area's unique geology was recognized in the middle of the nineteenth century by the US government, which designated the area a park in 1872. Within the park's protective boundaries, herds of buffalo and elk as well as other wildlife have survived hunting and loss of habitat to become today's thriving ecosystem.

    Yellowstone National Park
    Yellowstone Park Travel Guide
    Visiting Yellowstone National Park seems at times like visiting a place extraterrestrial, so foreign are the exploding springs of boiling water and smells of sulphur to our everyday experiences. Yet it is absolutely terrestrial, one of the few spots in the world to display such close interaction of the earth's surface with what lies underneath. I've heard this strange opinion expressed: "Yellowstone has become nothing more than an amusement park. It's not wilderness at all." Good heavens! There may have been times in its history when visitors seemed to believe they were at an amusement park or their local zoo: feeding bears, petting bison, and letting pets and children run around loose. But such actions are unwise. I can't think of a place I've visited that is more alien, or more dangerous. As for taming the park, it can't be done. Only one percent of the park is developed with roads and visitor services, and the caldera of an old, but still active, volcano sits in its midst... and who can tame a volcano?

    Exploring Yellowstone
    "Now that I’m here, where do I go?" It’s not an unusual question, especially for first time visitors. Consider the facts: Historically, visitors often referred to Yellowstone as "Wonderland," and that may be even more appropriate today. An unparalleled array of geothermal phenomena - geysers, hot springs, steam vents and mud pots - are preserved here, evidence of a volcanic past (and future?). The Grand Canyon of the Yellowstone is famous for its colors, shapes, and waterfalls (the Lower Falls, at 308 feet (103 m), is the highest in the park). The park shelters a variety and abundance of wildlife found in few other places. Yellowstone Lake and numerous rivers, streams, and waterfalls constitute a major Western water resource. The park's major scenic attractions are located along the Grand Loop Road, the roughly figure eight shaped road in the center of the park. The total mileage around the Loop is 142 miles (229 km). The distance around the Upper Loop is 70 miles (113 km); the Lower Loop, 96 miles (155 km). Actual driving time is difficult to estimate because the maximum speed limit is 45 mph (73 km per hour) or lower where posted, roads are narrow, winding, and full of pot holes and frost heaves, and traffic may be heavy and slow moving. While it is possible to drive the Grand Loop in a day, major attractions like Old Faithful Geyser and the Grand Canyon of the Yellowstone can only be seen by driving to a parking area and walking to the feature.

    Nancy and David fill us in on the latest leg of their journey. We catch up with them high up in the Bolivian mountains.
    Time to fill you in on what we`ve been up to. Our plans have taken a rather drastic turn. While we`ve been away Dave has been contacted by a company in San Diego and offered a job which we have decided is too good an opportunity to miss.
    As a result we`re going to have to cut the travelling short in time to set up camp in California by the 1st November. Hence we`re having to cut South America down to just one month, but we still have time to use up our mileage on the round the world tickets and fit in a week of diving in Fiji. So, since we finished the Inca trail here`s what we`ve been up to.
    Up in the mountains
    We left Cusco and headed straight to the Bolivian side of Lake Titicaca, the highest lake in the world at 4800m above sea level. The lake itself was very pretty, because it's so high up the air it is really clear and hence the lake is an amazing blue colour which is made to look even more striking against the white of the surrounding snow-capped mountains. After a day's boat trip to the Island of the Sun, from where the Inca religion stems, we settled down to our cheapest nights accommodation of the trip so far, which worked out at about 50 cents each. Even though we were just 10km from Peru the cost of living had dropped significantly.
