107 to entrance and 139 to Old Faithful.

That would be the eruption that formed the Lava Creek Tuff some 640,000 years ago. Ash was dispersed from the Baja Peninsula in a ring north through present day California, Oregon, north to North Dakota and lower Canada, east to Illinois, south to the Gulf of Mexico, and west across northern Mexico. This was the last super eruption. The most recent explosive event occurred 13,800 years ago and excavated Mary Bay (3.1 square miles) on the northeast boundary of Yellowstone Lake at the center of the caldera.

Yes, they are a big reason why Yellowstone was established. The last few hundred bison living in the lower 48 states lived there. Bison that have been reintroduced elsewhere in the US have ancestors in the Yellowstone herd that survived near-extinction.

there are an infinite amount of black bears in Yellowstone, they are sent from the homeland to Yellowstone each year to inhabit and mate and create more black bears thus creating a HUGE population of black bears.

Wolves can die by many things humans for one then there's disease, getting a kick to the head, old age, other wolves for pack boundaries and dominance, and many more things

The world renowned Old Faithful Geyser is hosted. I'd imagine this is the main reason it's so well known and attracts people

By the wolves not being there, the elck got very over populated, and they ate all the prairie dogs. The prairie dogs all died out and the plants that they ate, started to grow everywere.

Yellowstone National Park is the oldest national park in the world. It lies in the northwest corner of Wyoming. The park is a nature and wildlife preserve.Yellow Stone National Park also reaches into Idaho and Montana.

At the end of 2011, at least 98 wolves in 10 packs plus 2 loners occupied Yellowstone National Park. The population size (97 wolves) and number of breeding pairs (8) is the same as at the end of 2010.

This is merely the wolf population that exists in the park. There are a number more which have already moved out of thepark to take up territory in the surrounding area

Looking at attached image...the North America falls under Northern and Western Hemisphere. So Yellowstone National Park is in Northwest hemisphere.

The whole place, but center is hottest, it's the middle of the worlds biggest breathing supervolcano.

No. Most of Yellowstone lies outside of the Yellowstone Caldera, though this caldera still takes up a large portion of the park. A larger portion of the park is in the older Island Park Caldera, which partly overlaps the Yellowstone Caldera. This still takes up a minority of the park.

Yellowstone is known gloablly as the first ever national park, and perhaps the most well known. Its geoligical wonders and sheer beauty have captivated us for centuries.

UNESCO and The Man and Biosphere program decided to make Yellowstone a World Biosphere reserve because it is an environmental gem and is worth adding to the list of hundreds of protected biospheres.

During the summer of 1988, about 250 separate fires broke out in the greater Yellowstone eco-system. Most burned themselves out without causing noticeable damage. Seven fires became much larger than the others, and caused 95% of the nearly 800,000 acres of damage that summer. The largest, named the Shoshone Fire, was first noted on June 23, but it remained a minor event until about July 20.

Fire suppression after late July cost $120 million but did almost nothing to even delay the spread of the fires. Snowfall on September 11 finally ended the major damage, although the fires were still smouldering into November.

some things not many, but some can survive and thrive in areas that are inhabitable to most, such as hot springs or valcanic vents on the floor of the ocean where water temp maqy reach 1200 degrees and pressures would crush any human.

Yellowstone NP is a large area with widely varying climate -- some parts get twice as much as much rain as other parts. Note also that scientists do not total up "rain" so much as inches of total water that falls in an area -- whether or not the water fell in the form of rain or snow.

Old Faithful recieves an average of 24 inches of water precipitation each year, including 212 inches of snow.

the food web changed when the gray wolves disappeared from Yellowstone National Park because the population of the prairie dog got over populated

The Yellowstone Caldera is in Yellowstone National Park in northwestern Wyoming in the western United States.

That the Yellowstone volcano will erupt again in inevitable, but scientists do not know when. The volcano as it is now has only produced 3 super eruptions 2.1 million, 1.3 million, and 640,000 years ago this gives and interval range of 800,000 to 660,000 years. A smaller eruption occurred about 70,000 years ago. Given these intervals and the fact that scientists have not found any real evidence of an imminent threat, it is unlikely that it will erupt in our lifetimes.

The current population of lions in Yellowstone is estimated to be 18-24 animals and is thought to be increasing.

Antelope/Pronghorn is the fastest land animal at 60mph

Wolf - 40mph

Mountain Lion - 35mph

Bison/Buffalo - 30mph

Grizzly - 30mph
