Yellowstone National Park was established on March 1, 1872, Yellowstone is the first and oldest national park in the world and has been a blueprint for National Parks set up worldwide ever since . Preserved within Yellowstone are Old Faithful Geyser and some 10,000 hot springs and geysers, the majority of the planet's total. These geothermal wonders are evidence of one of the world's largest active volcanoes; its last eruption created a crater or caldera that spans almost half of the park.

An outstanding mountain wildland with clean water and air, Yellowstone is home of the grizzly bear and wolf, and free-ranging herds of bison and elk. It is the core of the Greater Yellowstone Ecosystem is one of the largest intact temperate zone ecosystems remaining on the planet.  Yellowstone’s grand vistas, huge mountains, deep canyons, roaring rivers, expansive lush meadows, high plains and abundant wildlife have been attracting photographers and sightseers from all over the world since William Henry Jackson sent home the first photos in 1871.

Geothermal Features: With half of the earth’s geothermal features, Yellowstone holds the planet’s most diverse and intact collection of geysers, hot springs, mudpots, and fumaroles. Its more than 300 geysers make up two thirds of all those found on earth. Combine this with more than 10,000 thermal features comprised of brilliantly colored hot springs, bubbling mudpots, and steaming fumaroles, and you have a place like no other. Geyserland, fairyland, wonderland, through the years, all have been used to describe the natural wonder and magic of this unique park that contains more geothermal features than any other place on earth. Yellowstone’s vast collection of thermal features provides a constant reminder of the park’s recent volcanic past. Indeed, the caldera provides the setting that allows such features as Old Faithful to exist and to exist in such great concentrations.

Yellowstone WildlifeYellowstone is widely considered to be the finest megafauna wildlife habitats in the lower 48 states. Animals found in the park include the majestic American bison (buffalo), grizzly bear, black bear, elk, moose, mule deer, pronghorn, wolverine, bighorn sheep and mountain lion (puma). The Yellowstone Lake Cutthroat Trout is a highly sought after trophy fish by anglers yet has been threatened in recent years by the suspicious introduction of lake trout that compete for spawning grounds and are known to consume smaller cutthroat trout.

A controversial decision by the U.S. Fish and Wildlife Service (which oversees threatened and endangered species, is the recent reintroduction of wolves into the park's ecosystem. For many years the wolves were hunted and harassed until they become locally extinct in the 1930s. The smaller cousin of the wolf, the coyote, then became the park's top predator. However, the coyote is not able to bring down any large animal in the park and the result of this lack of a top predator on these populations was a marked increase in lame and sick megafauna. Since the reintroduction of wolves in the late 1990s this trend has started to reverse. More about Yellowstone's Wildlife

Yellowstone; a science laboratory

The Yellowstone Super Volcano: The Yellowstone Volcano Observatory (YVO) was created as a partnership among the U.S. Geological Survey (USGS), Yellowstone National Park, and University of Utah to strengthen the long-term monitoring of volcanic and earthquake unrest in the Yellowstone National Park region. Yellowstone is the site of the largest and most diverse collection of natural thermal features in the world and the first National Park.

Volcanic History Overview: The Yellowstone Plateau volcanic field developed through three volcanic cycles spanning two million years that included some of the world's largest known eruptions. Eruption of the Huckleberry Ridge Tuff about 2.1 million years ago created the more than 75-km-long Island Park caldera. The second cycle concluded with the eruption of the Mesa Falls Tuff around 1.3 million years ago, forming the 16-km-wide Henrys Fork caldera at the western end of the first caldera. Activity subsequently shifted to the present Yellowstone Plateau and culminated 640,000 years ago with the eruption of the Lava Creek Tuff and the formation of the present 45 x 85 km caldera. Resurgent doming subsequently occurred at both the NE and SW sides of the caldera and voluminous intracaldera rhyolitic lava flows were erupted between 150,000 and 70,000 years ago. No magmatic eruptions have occurred since the late Pleistocene, but large phreatic eruptions took place near Yellowstone Lake during the Holocene. Yellowstone is presently the site of one of the world's largest hydrothermal systems including Earth's largest concentration of geysers.

Yellowstone Microbiology Research: Yellowstone National Park is a focal point for cutting-edge microbiology research and how it provides a valuable setting for outreach education. extremophiles, microbe diversity and evolution are studied here. Scientists who study extreme environments are drawn to Yellowstone because it contains more active geothermal features than any other location on the planet. Those features are also very diverse.. Geothermal environments are obviously very hot, but they offer a variety of chemical extremes, some of which are relevant to applications in bioenergy and bioprocessing.

Scientists found the bacteria, called Candidatus Chloracidobacterium termophilum, in Octopus and Mushroom springs and the Green Finger Pool, not far from Old Faithful. The bacterium grows best in temperatures between 120 and 150 degrees Fahrenheit and could help researchers drastically increase production of biofuels.

Summary

I have had the pleasure of living in the Greater Yellowstone Region since 1987 and I find new things every time I venture into the park. When I am not there I still marvel about the Yellowstone that comes to me via newspaper and computer. Dynamic is and understatement for a place that can both blow us up because of it’s volcanic nature or cure our cancer oddly enough because how its volcanic nature produces microbes that are pivotal in medical research.

As a photographer I find the place and its critters pure magic. As an inquisitor of life I find Yellowstone dynamics is pure fascination. As a fly-fisherman Yellowstone has proven to be Nirvana.
