BRIEF HISTORY OF YELLOWSTONE PARK

Yellowstone National Park got its name originally from French trappers in the area at the end of the 18th century.  They called the main river in this area "Roche Jaune" which was loosely translated later by 
American Trappers as "Yellow Stone", and thus the name Yellowstone River.  It is assumed that this name 
Lower Falls, Grand Canyon of the Yellowstone River, Yellowstone National Parkcame from the bright yellow-colored rocks of theGrand Canyon of the Yellowstone River.  When the area underwent consideration as the world's first national park, they elected to call it Yellowstone National Park, after the Yellowstone River whose headwaters are located there.


First Humans
Humans first came to the Yellowstone Park Region at least 11,000 years ago when Native Americans began hunting and fishing in the modern-day Yellowstone National Park.  Then white explorers first came close to Yellowstone Park during the Lewis and Clark Expedition in 1805 through Montana.  These explorers encountered Shoshone, Crow and Nez Perce Indians, and were told of the incredible land to the south, but neither Lewis or Clark pursued these claims.

Explorers / Trappers
Then in 1806, a member of the Lewis and Clark Expedition by the name of John Colter left the expedition and joined a group of fur trappers.  In 1807, after splitting up with these trappers, John Colter spent the winter of 1807-1808 and saw a steaming geyser near Tower Fall.  After barely escaping hostile Indians, he told of what he witnessed, but many thought we was simply suffering from delirium. 


During the next 40 years, trappers and mountain men who visited the area would speak of boiling water in these mountains, but again the public thought this was simply myth.  For example, in 1856 the famous mountain man Jim Bridger witnessed several geysers first-hand, but when he told people of the incredible things he saw, they dismissed it because Jim Bridger was known to tell tall-tales.

In 1860, guided by Jim Bridger,  Captain William Raynolds and Ferdinand Hayden came to the west for a two year project to survey the Northern Rockies.  However, when attempting to cross the continental divide between the Wind River Range and Yellowstone Park, they were stopped by snow and weather, otherwise they would have been the first organized expedition to explore the Yellowstone Park area.

The First Expedition
The first detailed expedition to Yellowstone Park in 1861.  Known as the Cook-Folsom-Peterson Expedition, these men floated the Yellowstone River all the way to Yellowstone Lake.  They kept a detailed journal, and 
Roosevelt Arch with Electric Peak, Yellowstone National Park
after reading it, a group of Montanans organized another expedition known as the Washburn-Langford-
Doane Expedition of 1870. This expedition included Henry Washburn (surveyor), Nathaniel P. Langford (Yellowstone Park's first superintendent), and Gustavus Doane (army commander).  They spent over a month in Yellowstone Park, naming landmarks such as mountains and rivers, collecting specimens, and exploring the area.


In 1870, Cornelius Hedges, a member of the Washburn-Langford-Doane Expedition and a Montana lawyer and writer, recommended publicly that Yellowstone be preserved as a National Park.  His words were the echo of the Montana Territorial Govenor Thomas Francis Meagher, who previously in 1865 recommended that this area be protected.

Hayden Expedition
Then in 1871, 11 years after his failed attempt into the region, Ferdinand Hayden led a government sponsored expedition into Yellowstone Park, bringing with him a photographer by the name of William Henry Jackson, and landscape artist Thomas Moran.  Hayden then compiled a thorough report, which included large-format photos and detailed paintings, and was able to convince Congress to act. On March 1, 1872, President Ulysses S. Grant signed the law that created Yellowstone National Park.


YELLOWSTONE PARK GEOLOGY 
Yellowstone "Super Volcano"

Yellowstone National Park is basically a giant active volcano.  It is the largest volcanic system in North America, and the opening of this volcano (known as the Yellowstone Caldera), is one of the largest calderas in the world.  But the Yellowstone Caldera isn't just a big volcano, it's what geologists call a "Super Volcano" because of how explosive and destructive its eruptions have historically been.

There have been a number of major eruptions through geological history, such as the massive eruption that occurred 2.1 million years ago where 588 cubic miles of volcanic materials were ejected, and 1.3 
Grand Prismatic Spring, Midway Geyser Basin, Yellowstone National Parkmillion years ago where 67 cubic miles of volcanic materials were ejected. The most recent cataclysmic 
eruption occurred about 640,000 years ago, where 240 cubic miles of debri were ejected.  The ash from this event covered a large area of North America, and actually caused animal extinctions.  This cataclysmic eruption was over 1,000 times bigger than the 1980 eruption of Mount St. Helens.  


Between 640,000 years ago and 70,000 years ago, there have been a series of "smaller" eruptions, where this debri and lava has filled in most of the present day Yellowstone Caldera.  Rivers such as the Yellowstone River and Lewis River have cut through these huge lava flows, resulting in deep V-shaped canyons such as the Grand Canyon of the Yellowstone.  To monitor the volcanic activity in Yellowstone National Park, in 2001 the U.S. Geological Survey, Yellowstone National Park, and University of Utah have teamed up to form the Yellowstone Volcano Observatory (YV0).

Earthquakes
Yellowstone Park experiences from 1,000 to 3,000 earthquakes annually, most of which are so small nobody notices them.  However there have been 6 earthquakes with a magnitude of 6 or higher, and the 
most infamous earthquake occurred in 1959 where a 7.5 magnitude quake hit just outside the northwest 
Sapphire Pool, Black Sand Geyser Basin, Yellowstone National Parkboundary of the park.  This quake caused the entire side of a mountain to collapse and block the Madison River just below Hebgen Lake, which created Quake Lake.


Geothermal Features
Yellowstone Park is presently home to over 300 geysers and over 10,000 geothermal features.  That's over half of the world's geothermal features and two-thirds of the world's geysers.  The largest active geyser in the world is Steamboat Geyser, which is located in the Norris Geyser Basin, and the most popular and visited geyser in the world is of course Old Faithful Geyser, which is located in the Upper Geyser Basin in Yellowstone Park near Old Faithful Inn.

YELLOWSTONE PARK ECOLOGY / BIOLOGY
Yellowstone National Park is over 2 million acres in size, and is the centerpiece of the enormous 20 million acre area known as the Greater Yellowstone EcoSystem.  This large, nearly intact ecosystem includes Grand Teton National Park, and the surrounding national forests and designated wilderness areas.  The Greater Yellowstone Ecosystem is regarded as one of the largest remaining continuous stretches of mainly undeveloped land in the United States.

Animals
Grizzly bears, Yellowstone National ParkYellowstone Park has over 67 mammal species, 322 bird species, 16 fish species with 5 being non-native, and 1,349 plant species, where all of the original faunal species that were present when white explorers first laid their eyes on Yellowstone Park, are still found in this incredible place.

Life Zones
There are eight "life zones" found in Yellowstone National Park, which include the Hydrothermal Life Zone, Marshland and Aquatic Life Zone, Northern Desert Life Zone, Sagebrush-Grassland Life Zone, Mixed Forest Life Zone, Lodgepole Pine Life Zone, Spruce-Fir Life Zone, and Alpine Tundra Life Zone.  Each of these zones provide a home to an incredibly diverse array of animal and plant life, and are much determined by the altitude of the land and the amount of annual precipitaton that particular area receives.

OLD FAITHFUL INN: THE ORIGINAL "PARKITECTURE"
Old Faithful Inn, Yellowstone National ParkThe design and construction of the Old Faithful Inn is known as Parkitecture, and it was the first of its kind. Since its construction during the winter of 1903-1904, national parks throughout the United States and the world followed this classic rustic design.

Old Faithful Inn is one of the most beloved structures in the United States.  In fact, in 2007 the American Institute of Architects conducted a survey of what Americans felt were the 150 favorite buildings in the United States. Old Faithful Inn ranked 36th.

Old Faithful was designed by 29 year old architect Robert Reamer. He wanted this building to be part of its surroundings, so most of the materials used to build the Old Faithful Inn were materials found in the immediate area, such as fallen and dried-out Lodgepole pine trees and Rhyolite stone.  Built in the winter of 1903-1904, it is still the largest log hotel in the world, and probably the largest log building in the world. Known as "The Old House", the Old Faithful Inn is truly a national treasure, and is a favorite destination for Yellowstone Park visitors year after year.
