Death Valley National Park was Very Different in the Past Essay

Yellowstone is the worlds first national park. It was origanally home to Native Americans who lived in the Yellowstone area for at least 11,000 years.The U.S. Army was first commissioned to oversee the park just after its establishment in late 1960. In 1917, administration of the park was transferred to the National Park Service. Yellowstone National Park spans an area of 3,468.4 square miles (8,983 km2), mostly comprising lakes, rivers canyons and mountain ranges. The national park is located primarily in the state of Wyoming, although it also extends into Montana and Idaho. It was established by the U.S. Congressand signed into law by President Ulysses S. Grant on March 1, 1872.

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

sand being deposited upon it. The only reason why beaches shrink is due to erosion and this

During the last 140 years the ecosystem of the Lake Tahoe Basin has experienced multiple alterations. Just as many areas have been depleted or implemented signs of struggle after initial European settlement the Lake Tahoe basin’s ecosystem has been vastly affected by man. The precedent environment of Lake Tahoe’s basin may never be restored to its original condition; however efforts are being made toward its restoration.

* The sand dunes on the beaches. This area is affected by wind erosion as well as the tides if adequate vegetative cover is not present. The main type of erosion, from the sea, takes the sand from the sand dunes as well as the rest of the beach in a rip. The sand is then pulled out to sea where it forms a sand bar. On calmer days, the sand is brought back to the beach.

First, we must examine the sedimentary formations; when they were formed, how they were formed, and what materials they consist of. About ninety-three to one hundred million years ago, the Western Interior Seaway rolled through the North American continent, eventually reaching the geographical area of today’s Mesa Verde National Park (National Park Service 2005). This sea deposited a thick, hard sandstone base that is called Dakota Sandstone, although this layer is not exposed in the park

Long Island is famous for its sandy ocean beaches. Between the barrier beach and the main coast is the Great South Bay. The beaches and dunes have very different characteristics. The sandy beach is the junction of land and ocean. The sandy beach consists of two zones, the swash zone and the drift line. The swash zone is the area of wet sand, caused by the incoming wave. The drift line is formed by the dead seaweed and other aquatic plants. Behind the sandy beach is the primary dune. The primary dune's main function is to absorb the force of the ocean and protect the great south bay and the island's main coast. In some cases secondary dunes form. These dunes are behind the primary dune and are therefor protected from the ocean. This provides the stability necessary for plant growth. Many time a maritime forests will form on secondary dunes.

As a historically semi-arid environment, California has also suffered heavily from several environmental impacts as a result of the current drought conditions. The first of these is on its forests. The US Forest Service estimates that 12 million trees have died in the past year due to drought; this combined with the drying of forest floor material greatly increases the flammability of the landscape. The result of this is the numerous devastating wildfires that have swept through the state throughout 2015, costing not only wildlife and habitat but also human property (CBS News, 2015) (Lustgarten, et al., 2015) (Google, 2015). Aside from wildfires, the drought and associated loss of habitat is said to be having a negative effect on both flora and fauna due to their contribution to the spread of West Nile Virus, whilst also threatening populations of geese, ducks, salmon and Joshua trees (Lustgarten, et al., 2015) (Beaudry, 2015). Finally, with groundwater contributing up to 50% of stream flow in drought, there is a worry that over usage near the coast could result in irreversible salinization through the drawing in of salt water (USGS, 2016) (Kasler & Reese, 2015).

In conclusion, Withlacoochee River Park is vitally important to Florida’s natural habitat. The lack of industrial development of the Green Swamp and the areas that make it up have led to a biological haven for a plethora of species and allowed for near pristine water conditions. The ecological importance of this geographical location is tremendous, and if we lost it to development or pollution, it would be a great loss for the state of

The Natural History Museum of Los Angeles offers a surface level depiction of Mesoamerican civilization and culture. It excludes essential information and instead gives a shallow representation that offers implications of a barbaric civilization.

Environmentalism has always been two sided. Nature versus urban. locals versus national. Frequently, large tracts of public and federal land are bought and developed by industry. Pristine wilderness turned to bustling epicenters of human activity, all in the name of progress and economic growth. This tale of preserving natural wilderness is one that begins with John Muir, an advocate against the taming of Yosemite national park and the Hetch-Hetchy reservoir, while the head of the US Forest Service, Gifford Pinchot, insisted on the reservoir to supply the city of San Francisco with water. This timeless epic of conservation or preservation brings us to the Jumbo Valley, a vast expanse of uninhabited, pristine wilderness home to diverse

Reportedly the tallest single-structured sand dune in North America rises to 470 feet (140 m) high above small lakes. The dunes at Bruneau Dunes State Park are unique in the Western Hemisphere. Other dunes in the Americas form at the edge of a natural basin. The Bruneau dunes form near the center. The basin has acted as a natural trap for over 12,000 years. The dunes may have started with sands from the Bonneville Flood about 15,000 years ago. The prevailing winds blow from the southeast 28 percent of the time and from the northwest 32 percent of the time, keeping the dunes fairly stable. Unlike most dunes, these do not drift

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.
