Yellowstone Report (Sean)

Yellowstone National Park is located in Wyoming in America. There are precisely fifty-six National Parks in America! Yellowstone was the first in the country opening on the 1st March 1872. Yellowstone is an active Volcano, (one of the largest, and most violent on earth) made up of Waterfalls, Wildlife, Geysers, Hot Springs, Fumaroles and Mud Pots!  Every Geyser, Hot Spring, Mud Pot, and Steam Vent has a unique name. Example: Pearl
Geyser or Mystic Spring. Some look like the namesake. Others do not!


There are just about one thousand geysers in the world and more than five hundred of them are located in Yellowstone. Yellowstone has many Geysers such as “Old Faithful” the most famous, which for seventy-five years has erupted every hour or two of each day! They can tell when the next one is going to erupt by timing how long the previous one went off for. This represents the amount of water passing through it and using a calculation they
can time when next eruption will be. This only works with Old Faithful. Since the 1950’s the people of Yellowstone have been able to predict when it will go off, but the average time between eruptions has increased, partly due to earthquakes.


“Hot Springs”

In Hot Springs, water flows freely to the surface. The colours come from minerals – tiny, heavy loving life forms – and retracted light. The biggest Hot Spring in Yellowstone is The Grand Prismatic Spring and is also the brightest!

“Fumaroles/Steam Vents”

Fumaroles or Steam Vents are Geysers with small amounts of water. It flashes into steam
before it reaches the surface, producing a hissing noise. The fumaroles are the hottest hydrothermal feature in the park!

“Mud pots”
Mud Pots are the result of acid water and melted rock turning into mud and clay. When
it’s time, they boil up, producing a rotten egg smell.  These are what tell us the Yellowstone volcano is still active!


Every year approximately 2,500 earthquakes occur in Yellowstone! Although this many earthquakes happen each year in Yellowstone, they are often too week to feel. Earthquakes are another sign of  volcanic activity!

One very important piece of information is that “Geysers Need Earthquakes.” Earthquakes can change the shape of Geysers and Hot Springs. They can cause Hot Springs to erupt like Geysers, and Geysers to become (more like) new hydrothermal features!

To detect the earthquakes, the movement of hot water creates stress creating earthquakes. Yellowstone’s earthquakes are detected by a seismograph. The earthquakes shock wave shakes the earth’s surface, sometimes causing great destruction.

Yellowstone is also one of the biggest National Parks standing at 2.2 million acres with
five main Ranger resorts at “Mammoth Hot Springs, Old Faithful, Canyon Village, Grant Village, and Lake Village.

20,000 years ago The Canyon Village area was covered in 4000 feet of ice! Glaciers
have covered Yellowstone for the past 2 million years. Unluckily, The Hot pots played a part by elevating the Yellowstone area. The increased elevation made Yellowstone cold enough for massive glaciers to form locally. These glaciers made Yellowstone’s landscape what it is today!

The most common animal in Yellowstone is Bison and has been present in the region for thousands of years. At the moment there is close to 3000 bison in Yellowstone. Bison often travel in herds of 25. In the Winter the Park is closed to tourists and the Bison and other keep warm around the Hot Springs and Geysers in the snow.

For animals such as Grizzly Bears and Wolves that cause trouble (get into human garbage) or get injured in Yellowstone (and other spots in America) they get transported to the Grizzly and Wolf centre in West Yellowstone. They keep them there until they are better or if they don’t reintegrate properly they stay there for good.  New bear proof bins are tested on these bears. If they can’t open it in ninety minutes then it’s passed the test. There is also a new eagle centre. This way, the animals of Yellowstone will stay safe and comfortable when injured!

I consider Yellowstone National Park to be the best in America for sheer size and
variety of life, landscape and animals.
