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.

Below I have listed a few of Yellowstone’s embarrassment of riches and provided links to the thumbnails but these barely scratch the surface of what is the comprehensive Yellowstone National Park.

Human History: The human history of the park dates back 12,000 years. The events of the last 130 years of park history are reflected in the historic structures and sites associated with various periods of park administration and visitor facilities of essay

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. -------------------> Rest of essay

Wolves eating buffalo in Yellowstone National Park
Wolf eating bison,, Yellowstone National Park

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

The Yellowstone Fires of 1988

Yellowstone Fire
Yellowstone Fire of 1988

Fire is good; Yellowstone has long been shaped by fire and not just the cool, creeping ground fires often described as "good" for grass production. The natural history of fire in the park includes large-scale conflagrations sweeping across the park's vast volcanic plateaus, hot, wind-driven fires torching up the trunks to the crowns of the pine and fir trees at several hundred-year intervals. It is supposed to be this way. During the first half of the twentieth century, most people, forest managers included considered forest fires to be destructive and without positive value. For this reason, Yellowstone and throughout the National Park Service had a policy of putting out all fires on national interest wildlands lands. In the second half of the century, forest managers of national parks and forests began to understand the importance of periodic wildland fires. With the help of Smokey the Bear most of America was in consensus that all wildfires were bad. Most Americans steeped in Smokey the Bear's "Only you can prevent forest fires!" mantra, the very thought that forest fires might have a positive side seemed preposterous. We all learned this as children and it is damned hard to change, as our indoctrination to this policy was total. Unfortunately man’s past practice of total forest fire suppression has changed the forest into a much shadier forest floor habitat causing heavy fuel accumulation on the forest floor resulting in the very hot forest fires we see lately that result in maximum loss of the forest. The Natural Burn Policy The National Park Service interprets its mission as letting natural processes play out unimpeded by man. Biologists and park managers have defined its policy: "We allow a park that has documented the role of fire as a natural part of the ecosystem, and that has an approved fire-management plan specifying the prescriptions under which natural fires may burn, to manage each fire on an individual basis.".....................  Read rest of essay

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. ...................Rest of essay

Thermophile microbe researchers in Yellowstone
Thermophile microbe researchers in Yellowstone

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.

Researchers looking at bacterial mats in Yellowstone’s thermal pools discovered a new species that uses chlorophyll to convert the sun’s energy into chemical energy.

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.................... Rest of essay

Hot springs and thermophile bacteria, create pretty colors


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 I 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.

The Greater Yellowstone Resource Guide suports Wyoming Wildlife Advocates. Wyoming Wildlife Advocates formed to promote a rational, science-based approach to wildlife management throughout the state of Wyoming. WWA will encourage policies that will maintain a healthy, natural balance — or dynamic equilibrium —between predator and prey species. We acknowledge that fluctuations occur among populations, but we believe this is natural and that the hand of man must lay lightly upon the reins.

"Warrior and living legend, Joe Medicine Crow, wants President Obama to protect the Crow's "Brother Grizzly".

CROW AGENCY—As the Crow Nation prepares for the 97th Annual Crow Fair Celebration, the tribe's centenarian and "living history," Dr. Joseph Medicine Crow, wants those about to transform Crow Agency into the "Teepee Capital of the World" to remember a brother of the Crow people who is in need.

"Grizzly bears, we call them our brothers," says Dr. Medicine Crow. "They play an important part in our culture and we'd like to keep it that way."

Dr. Medicine Crow's comments are in response to the Obama Administration's US Fish and Wildlife Service (FWS) that is expected to announce a new rule this fall to delist the Yellowstone grizzly bear from the Endangered Species Act (ESA). Delisting the grizzly will enable the states of Montana, Wyoming and Idaho to open trophy-hunting seasons on the bear, a being many tribes consider sacred..... Rest of Article

Death of a Man. . . Death of a Bear
By Keith Crowley

Trying to make sense of last week's fatal Grizzly bear attack on a hiker in Yellowstone National Park and it's aftermath is a fool's errand. But this fool is going to try anyway.

This kind of story wrenches it's way deep into the psyche of all who spend time in the wilds. And it certainly wrenched its way deep into my soul since I spend months each year in Yellowstone and the surrounding Grizzly Country. To make it even more personal, ... rest of article

Yellowstone roadside grizzlies worth rangers' hassle???

Yellowstone visitors would pay an additional $41 to ensure seeing roadside grizzlies, a study shows, and the attraction creates 155 jobs and more than $10 million a year for the regional economy. The $41 visitors would pay is on top of the $25-per-vehicle entrance fee. If Yellowstone no longer allowed grizzly bears to use roadside habitat — and instead chased, moved or killed them — the regional economy would lose more than $10 million a year and 155 jobs according to the paper "The economics of roadside bear viewing."............................Rest of story

A Case for CollarsBy Keith Crowley

As a wildlife photographer I have a real love/hate relationship with radio telemetry collars.  All photographers live in a world of aesthetics, and most wildlife photographers try capture natural animal behavior in natural settings with as little apparent human influence as possible. Even something as ephemeral as a jet's vapor trail in the sky can destroy a wild image. The permanence of collars (and ear tags, too) placed by human hands on wild animals is impossible to ignore.......................For my part, I think are few truly valid reasons not to collar wolves in Yellowstone. But there is also one really good one, and in the interest of open discussion, some points are worth of story

Helpful ebook for photographers

The Grand Teton Photo and Field Guide is an encapsulation of the flora, fauna, and photography of Jackson Hole Wyoming and Grand Teton National Park. Also included are thumbnails of the history and geology of the valley. This book is for all visitors with a desire to seek out wildlife, photograph the landscape, or merely learn about the history, geology, and lay of the land of Grand Teton National Park. The author provides general overviews including hot links with more in-depth descriptions of subjects of individual interest.

In the “Lay of the Land” section, includes the obvious highlights along the loop through Grand Teton Park. Hot links to side roads will give you more in-depth description of side roads and feeder roads and their highlights. Also included are descriptions of all two-rut roads that are legal to travel on in Grand Teton Park. GPS links to Google Maps are provided throughout.

As a field guide, profiles of most of animals and birds in the area are described. Jackson Hole is full of wildlife but there are places where animals are, and there are places where they are not. It is a waste of time to scrutinize a landscape devoid of what you are looking for, so this guide narrows options down to the hot spots. I provide maps of the likeliest places to find the popular critters of Grand Teton National Park. I also touch on trees, shrubs, and wildflowers with minimal explanations.  

The grandeur of Grand Teton Park has made it one of the most photographed places in the world. The opportunity to harness multiple juxtapositional elements has drawn photographers for over a century since William Henry Jackson took the first photos here in 1878. Grand Teton Park’s plethora of famous vistas are profiled as well as many which are less clichéd that can bring new perspectives of a well-documented landscape. Grand Tetons’ iconic landscape photo opportunities are described in detail; however, they barely scratch the surface of opportunities as it takes a photographer with an artist’s eye to unveil as they follow their own intuition and vision.  The author who shies away from clichéd landscapes provides a chapter of his favorite places that aren’t landscape clichés.

In the photography section the author includes chapters on composition, exposure basics, when to shoot and why. Daryl has summarized what he teaches in his, half day, Grand Teton workshops in a simple concise way.

If you are only in Grand Teton Park for a day there is a chapter called the “Portfolio Packer Morning Trip,” that does just that, all the icons and several favorite places in a five our blitz.  But it is better to spend more time and dig deep into the embarrassment of riches of Grand Teton National Park.................
