The National Park Is One Of The Most Well Known National Parks

Established as a National Park in 1933 under President Franklin Delano Roosevelt, Death Valley is the largest national park in the continental United States even though its total length is no more than approximately 100 miles in length. The valley is located in the Mojave Desert in eastern California and is surrounded by the Amargosa Range on the east, the Panamint Range on the west, and the Sylvania Mountains and Owlshead Mountains on the northern and southern boundaries. The topography of this region is varied and complex; and has a lengthy geologic history that explains why it is riddled with a variety of sand dunes, craters, and flood-carved canyons to name a few. The total area of the valley is

Yosemite National Park, is a beautiful piece of nature it is a 195 mile nature getaway from the urban life that is lived San Francisco, CA and 315 miles away from the fast pace and overwhelming life that is lived in Los Angeles CA. This place is like no other in the beauty of its nature. The park is “747,956 acres, and is the home to hundreds of wildlife species and thousands of Yosemite plants” (U.S. Nat. Park Service). Yosemite is known for so many beautiful features, from its granite cliffs, waterfalls, clear streams, giant sequoia groves and biological diversity. And also for its two rivers which are the Tuolumne and Merced rivers. These rivers begin in the park and flow as far as west to the

Yellowstone National Park is one of the largest and oldest national parks in American history. Yellowstone was the first park to be protected by private investment on March 1, 1872, and the first to be put under the jurisdiction of the National Park Service in 1918, no doubt due to its unique and inspiring landscape and geothermal features. In fact, Yellowstone National Park is home to half of the world’s total hydrothermal features. These awesome attractions draw an incredible amount of visitors, an average of two to three million each year, to Yellowstone’s immense landscape. The park has a total size of 28,125 square miles, is found in three distinct states, and is considered to be one of the largest

The west coast of North America has been tectonically and volcanically active for billions of years. The Sierra Nevada Mountains in eastern California were born of volcanoes, and magma has been erupting in the Long Valley to the east of the mountains for over three million years (Bailey, et. al., 1989). However, the climactic eruption of the region occurred relatively recently in the region's geologic history. About 760,000 years ago, a huge explosion of magma warped the Eastern Sierra into the landscape that exists today. The eruption depleted a massive magma chamber below the earth's surface so that the ceiling of the chamber imploded, forming what is now known as

The Sierra Nevada, Southern California, Idaho, and Coast Range batholiths formed as a result of which orogeny?

About 225 million years, all of the world’s land was contained in one supercontinent, named Pangea. This supercontinent would eventually separate itself into the continents that are known today, due to continuous movement of the earth’s tectonic plates, which led to major shifting and folding of the earth’s crust. This shifting formed many of the mountain ranges that exist today, such as the Appalachians and the Rocky Mountains. However, the time of Pangea’s separation into multiple continents and the time of the formation of the mountain ranges aren’t synonymous; for instance, the Appalachians were most likely formed before Pangea’s separation. About some 2 million years ago, a Great Ice Age befell the earth, which caused a

Yosemite was first protected in 1864 by Abe Lincoln,but it was actually a park in 1890 buy Robert Johnson and John Muir.You can find Yosemite in the granet heart of California (in the middle).But with in 12 acres wide!In the center of California.”What makes Yosemite a special place?” you might ask, well Native americans were the first people to live for a long time of the Valley.At Yosemite you can go hiking,backpacking, camp, tours with rangers,interpretive programs, and biking.Or you can visit waterfalls and glaciers.Can you believe this that a waterfall is as tall as 2 ½ thousand feet drop good luck taking a shower with that.Yosemite National Park became a National Park because of

In regards to the geologic components of Yosemite National Park, it essentially has two main parts. The first part is the deposition and deformation of the metamorphic rocks and the emplacement of the granitic rocks during the Paleozoic and Mesozoic periods. The second part is the uplift, erosion, and glaciation that took place with the rocks during the Cenozoic period. Yosemite National Park is relatively helpful in regards to observing the display of its geologic changes. When the Cretaceous period was ending which was roughly 65 million years ago, the granitic core of the range started to become

First, everything was a giant land mass, then it started separating into the continents and oceans formed in between. We know this because the same species of fish live in waters that are very far apart from one another. By 10 million years ago the basic shape had been created. All the moving of the earth’s crust caused it to push up mountains, the Appalachians are probably older than the continental split, the rest of the mountains (in U.S.) are newer.

On May 18, 1980 Mt. St. Helens erupted, and wrecked havoc on its surroundings through the debris avalanche, the lateral blast, the mudflows, and the ash that traveled halfway across the United States. It all began in March of 1980 when a 4.2 earthquake and 174 aftershocks let the world know that the volcano had woken

Yosemite National Park, founded in 1890, thanks largely to the efforts of John Muir, is 748,000 acres situated in the Sierra Nevada mountain range within the state of California. The park, home to over 400 species of animals, five separate forests and zones, eight types of rocks and cliffs, and nine waterfalls, attracts many visitors. The park’s landscape changes with the seasons; there is also a variety of activities that visitors can participate in depending on the season and weather. The National Park Service strives to preserve Yosemite; it is home to many threatened and endangered species, wildflowers that only exist in Yosemite, and all the park’s geological features and natural beauty should not be harm by man.

Lava flows of rhyolite and basalt have flowed through parts of Yellowstone as recently as 70,000 years ago. These lava flows destroyed everything in their paths while moving slowly at a rate of a few hundred feet per day, flowing months, or sometimes even several years. They are thick and cover as much as 130 square miles. They have nearly filled the Yellowstone Caldera, and spilled beyond the caldera’s border. These lava flows are responsible for forming four of the nine named plateaus in

The Grand Canyon has plenty of volcanic rocks near the bottom and the top. ICR, Institute for Creative Research, has been involved in a project for years to date these volcanic rocks. this study has come a long way to show that many of the Grand Canyon strata could have formed rapidly, and that the erosion of the Canyon by the Colorado River has not been going on for millions of years.

* Measurements of Geologic uplift and slip rates – in many areas of the San Andreas Fault a detailed record of strike-slip activity is provided. By studying the sediments deposited in a given area and comparing them to an established age control it is possible to determine the rates and timing of changes of tectonic deformation.

Our nations incredible 401 National Parks are some of the most iconic places on the face of the earth. From the Grand Canyon to the Great Smoky Mountains our nation's national parks are something we should be proud to have. Lately our National Parks have been under threat from both Environmental and Political issues both putting our National Parks at risk. We need preserve the National Parks for generations to come. The National Parks show the most amazing parts of this great nation, they are the source of billions of dollars in revenue, and they are the home to countless forms of wildlife.
