Establishing The Grand Teton
National park
In 1929 and in1950 the Grand Teton, which by the way was named by
French trappers, became Grand Teton National Park. In Febuarey1929
congress and President Calvin Coolidge started the park, which was
much smaller, then it is today. At that time the park was 96,000 acres
that only had the Teton Range and six lakes at the bottom of the
mountain. On September 14th, 1950, congress and President Harry S.
Truman started a “new” Grand Teton National Park. The new National
Park included the national mountain, creating the 310,000-acre park we
have today. It was established for people to see the beautiful wild life and
scenery.

In The beginning
 The Grand Teton started forming 100 million years ago through the collision of
tectonic plates. 10 million years ago the movement of the Teton faults caused
many large earthquakes up to 7.5 in magnitude. The earthquakes made the
west side land of the fault rise forming mountains and the eastside of the land
formed a valley. The measurement from the top of the mountain to the Valley
is approximately 30,000 feet. 2 million years ago glaciers as large as 3,500 feet
thick filled the valley causing erosion of the mountains. The glaciers made the
landscape of the peaks of the canyons. At the bottom of the canyons the ice
created basins that are lakes today.

 The Grand Teton National Park has had many different kinds of rock that, are all
different. 2.5 billion years ago the national park had crystalline rock, to be exact MT
Moran Gneiss and MT Owen granite. 550 million years ago all the way to 2.5 million
years ago, the national park was filled with an ancient sea that had sand Stone, Lime
Stone, Shale, Marine and non- Maine, and Sediments. 70 million years ago
volcanoes were ware the Grand Teton National Park that had volcanic rocks at that
time. 9 million years ago glaciers made lake sediment rocks in the Grand Teton
National Park. Those are some of the beautiful and extremely interesting rocks at
the Grand Teton National Park.

Environmental Changes In The Park
 Although the mountains and the land are healthy, the wild life in it is
still in danger. Climate change is a major environmental issue that is
affecting the park. For Example, Pine Bark Beetles are killing trees
because the heat is destroying their homes. The Pica, the smallest
bunny in the rabbit family, do not survive in weather over 80 degrees.
They are being forced to move up the mountain, which has cooler
temperatures, to survive.
The Land Inside The Park
 The land inside the park is currently changing because of glaciers and
fires. There are 10 glaciers but because of the temperature they are
getting smaller. Although the glaciers are getting smaller the Grand
Teton range of mountains is still growing because of the forces that
created it. The harsh wind, water and ice continues to wear down the
mountain. The Grand Teton National Park has many wild fires.
Although you might think it is bad for the environment, it is actually
helpful to the land in some ways. The land has too many trees. The
fire eliminates some of them.

Technology In The Grand Teton National
Park
 There are a variety of technologies used to preserve and maintain The
Grand Teton National park. The park used cement to make sidewalks
and tractors to make trails so people will walk on the trails and not
harm plants and animals. Recycling centers throughout the park
encourage visitors to recycle. The centers usually collect 170 tons of
material a year. Technology allows this material to be recycled. By
picking up the garbage the park maintains and preserves the
environment. Finally, to help assist the air quality of the park, signs and
park rangers request that when driving in traffic jam car engines should
be turned off.

Special Landforms
The Grand Teton National Park has many
beautiful landforms. Jackson Lake, one of
the many lakes in the park is the biggest
lake. Jenny Lake was made when the
glaciers of the Tetons melted. The Grand
Teton Mountains and Mount Moran both
formed from an earthquake fault. The
landforms on the eastside of a fault moved
down which made the valley of Jackson
Hole. Then, land on the west side of the
fault was pushed up which made the Teton
Mountains. Snake River is another beautiful
landform that gets its source from
Yellowstone Park. The Sagebrush Flats cover
most of the valley of Jackson Hole. Some
other beautiful landforms that people often
hike are Hidden Falls, Cascade Canyon and
Berry Creek.
