Lecture 8 - February 11, 2004 Previous or Next lecture Thermal environments in Yellowstone National Park We'll be talking about a wide variety of thermophilic organisms in this course, and many of these were originally isolated from the hot springs of Yellowstone National Park. Today, then, we'll talk about Yellowstone and the general features of hot spring environments, and have a look at some of the specific springs from which many of the organisms we'll be talking about grow. Yellowstone National Park Yellowstone National Park ocupies about 6000 square kilometers of the northwest corner of Wyoming, and was established as the world's first national park in 1872. Although YNP is renowned for it's scenery and wildlife (especially bears, which are now scarce in the park), the main attractions are it's geysers, hot springs, and fumaroles. The central region of the park is predominated by a 46 by 77 kilometer caldera (volcanic basin) formed by volcanic eruptions 1.8, 1.2 and 0.6 million years ago (notice the timing - we're due!). Hot springs, geysers, solfataras, and fumaroles

62. Hot Springs Some of the hot springs are spouting springs or geysers, the most famous being Geysirin Haukadalur in south Iceland, from which the international word geyser http://www.iceland.is/embassy/icelandis.nsf/form/content.html?openForm&wt=4B0130

Bacteriology at UW-Madison Bacteriology 303: Procaryotic Microbiology Life at High Temperatures by Thomas D. Brock Biotechnology in Yellowstone The thermophilic bacteria that live in the Yellowstone hot springs have been the foundation of impressive developments in medicine and biotechnology. The unique thermostable enzymes of these bacteria are finding wide industrial and medical use, and have become the basis of a multimillion dollar industry! When researchers began to study the biology of Yellowstone hot springs in the 1960s, the presence of these hyperthermophilic bacteria was not suspected. The upper temperature limit for life was thought to be around 73 degrees C (163 degrees F), which was actually the limit for photosynthetic organisms such as cyanobacteria. The preferred temperature for thermophilic bacteria was considered even lower, around 55 degrees C (131 degrees F). Because of the known effects of heat on biological structures such as proteins and DNA, it was thought that life at higher temperatures would be impossible. In fact, biochemists have known for over 100 years that enzymes (key cellular proteins) are destroyed by boiling. However, field observations in Yellowstone showed that in certain springs bacteria existed at much higher temperatures. Although these springs were rather small and not especially conspicuous among the impressive geysers and giant hot pools of the Yellowstone thermal basins, they were impressive microbial culture systems and turned out to be of great scientific and intellectual interest. It turns out that the enzymes of Yellowstone thermophiles are very tolerant of heat and are active even at boiling water temperatures.

Bacteriology at UW-Madison Bacteriology 303: Procaryotic Microbiology Life at High Temperatures by Thomas D. Brock 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.

Home Post Fourteen Post Fourteen - Sheep and Hot Springs Sue, the Wonder Herder Meet Sue of Greg's Sheep-n-Show, a tourist attraction that enlightens the public about sheep husbandry. We arrived on a drizzly, humid day, the sole ticket holders for the 1 p.m. show. Greg, a wiry, ebullient man, gave us his undivided attention for 90 minutes. We learned how sheep dogs are trained, how they herd sheep, and how they live. We sheared sheep, petted and fed lambs, and culled (sorted) the flock. I learned a lot that day about sheep, but I learned even more about dogs. Pam, Sue, and Dick were the tenacious canine herders that kept the flock in line. They were bred to work, they lived to work, and they were attuned to Greg in a way that was eerie. They instantly picked up on a look or the flick of his hand. Greg used unique command words for each dog (e.g., "here" for Dick to come, "come" for Sue to come), and they would not respond to each other's words. In fact, they wouldn't even respond to Greg using the correct commands in the wrong tone of voice, or when someone other than Greg used the correct commands. They were perfectionists who would not be distracted from their tasks. It was a sight to behold. After watching this troupe in action, I understand better why so many dogs bred to hunt and herd become hyperactive, uncontrollable house pets. If they can't work, they must go mad.

I first stopped in what passed for the centre of Gardiner (essentially a main street with buildings on one side, and Yellowstone on the other), to see whether there was a place that could sell me a new camera battery, as I had been getting some slightly suspect light meter readings the previous day. Mission successfully completed, I continued on, passing through the monumental Roosevelt Arch which spanned the main road into the park (Theodore Roosevelt having been a keen proponent of what became the National Parks Service, and later had a park named after him in North Dakota). I stopped a few miles into the park at Mammoth Hot Springs, essentially a small town which serves as the park headquarters, as well as providing numerous visitor facilities. I went into the visitor centre to pick up some information above that which I had been given at the park entrance, then made my way across to the lower terraces area. This is a splendid array of hot springs, but with the unusual property that as the water reaches the surface, it deposits dissolved minerals in the form of fantastic travertine terraces.

Anthropological commentary by LISE SEDREZ DAY THREE: leaving Yellowstone Another morning ride (by car this time) in Yellowstone. Early morning is the best time to see the park: very few tourist, and more animals around, sometimes very close to the roads. We saw a big elk, no more than 25 meters from the road, and a lot of bison (on the road). But this time it was the landscape that impressed us most. Yellowstone has huge valleys with grass only, and hills full of pines, and very beautiful creeks, side b y side with this exquisite moonlike landscape, with hot springs, and mudholes. Sometimes you see bubbles in the lakes and steam coming out of the creek, and you know there is a hot spring there. The animals don't seem a bit disturbed by this unique composition. Just the opposite. In Mamoth Hot Springs, we saw two families of pronghorn deer calmly resting by the hot springs, paying no attention to the tourists in the walk boards (due to the very thin crust around them, the hot springs are off limits to tourists). We also saw all around the park full, huge hill with burned, dead trees. From far away you see the grey hill mixing with the healthy green ones, and you know that this is a reminder of the 1988 fires.

National Geographic's Guide to the Lewis and Clark Trail National Geographic Books Begin by leaving your car in the parking lot at Old Faithful. Check at the visitor center for predicted eruption times of the major geysers. While there, pick up an Upper Geyser Basin map (also available from area dispensers). Wait on benches near the visitor center for the eruption of Old Faithful (named and celebrated for its steadiness rather than a predictable schedule of eruptions) or walk the path that circles it. Almost any point along the path offers a good view of the eruption so don’t worry if you’re not at the benches when it happens. You can see from here that Old Faithful is not alone. The mile-long [1.6-kilometer-long] Upper Geyser Basin contains the world’s greatest concentration of hot springs and geysers.

RETURN TO THE HOMEPAGE Articles Weekend FT (Financial Times) "How to Spend It" - March 2000 State of Bliss 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).

Home Page 1998 Yellowstone Pictures Inspiration Point, Yellowstone National Park 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.
