This is from Wikipedia : Death Valley National Park is a national park in the U.S. states of California and Nevada located east of the Sierra Nevada in the arid Great Basin of the United States. The park protects the northwest corner of the Mojave Desert and contains a diverse desert environment of salt-flats, sand dunes, badlands, valleys, canyons, and mountains. It is the largest national park in the lower 48 states and has been declared an International Biosphere Reserve. Death Valley National Park is visited annually by more than 825,000 visitors who come to see its diverse geologic features, desert wildlife, historic sites, scenery, and clear night skies.

It is the hottest and driest of the national parks in the United States. The second-lowest point in the Western Hemisphere is in Badwater Basin, which is 282 feet (86 m) below sea level. The park is home to many species of plants and animals that have adapted to this harsh desert environment. Some examples include creosote bush, Bighorn Sheep, Coyote, and the Death Valley Pupfish, a survivor of much wetter times. The park covers an area of 5,270 square miles (13,649 km2) of which 5,194 square miles (13,452 km2) is federal land. Approximately 95% of the park is a designated wilderness area, which covers 4,774 square miles (12,360 km2), making it the largest in the contiguous 48 states, and the sixth largest in the United States overall.

A series of Native American groups inhabited the area from as early as 7000 BCE, most recently the Timbisha around 1000 AD who migrated between winter camps in the valleys and summer grounds in the high mountain ridges. The first documented non-Native Americans to enter Death Valley did so in the winter of 1849 looking for a shortcut to the gold fields of California. They were stuck for weeks and in the process gave the valley its name, even though only one of their group actually died there.

Mining was the primary activity in the area before it was protected. Several short-lived boom towns sprang up during the late 19th and early 20th centuries to exploit minor local bonanzas of gold. The only long-term profitable ore to be mined, however, was borax, a mineral used to make soap and an important industrial compound. Today, borax is an essential component of high-temperature resistant boro-silicate glass products, for example some Pyrex glass products. Twenty-mule teams were used to transport ore out of the valley; helping to make it famous and the subject of books, radio programs, television series, and movies.

Tourism blossomed in the 1920s, when resorts were built around waters sources at Stovepipe Wells and Furnace Creek. Pacific Coast Borax, a major landowner, and others like Death Valley Scotty promoted the region. Death Valley National Monument was declared a U.S. National Monument in 1933, placing the area under federal protection. In 1994, the monument was redesignated a national park, as well as being substantially expanded to include Saline and Eureka valleys.

The natural environment of the area has been shaped largely by its geology. The valley itself is actually a graben. The oldest rocks are extensively metamorphosed and at least 1.7 billion years old. Ancient warm, shallow seas deposited marine sediments until rifting opened the Pacific Ocean. Additional sedimentation occurred until a subduction zone formed off the coast. This uplifted the region out of the sea and created a line of volcanoes. Later the crust started to pull apart, creating the current Basin and Range landform. Valleys filled with sediment and, during the wet times of glacial periods, with lakes, such as Lake Manly.

The park covers 5,262 square miles (13,630 km2), encompassing Saline Valley, a large part of Panamint Valley, almost all of Death Valley, and parts of several mountain ranges. The bulk of the park is in southern Inyo County and northern San Bernardino County in Eastern California. A small triangular extension near Rhyolite, Nevada of approximately 400 square kilometres (150 sq mi) is part of southwestern Nye County and extreme southern Esmeralda County in Nevada. In addition, there is an exclave (Devil's Hole) in southern Nye County administered by the Park.

USA - Nevada - Hoover Dam

This is from Wikipedia : Hoover Dam, once known as Boulder Dam, is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the US states of Arizona and Nevada. It was constructed between 1931 and 1936 during the Great Depression and was dedicated on September 30, 1935, by President Franklin Roosevelt. Its construction was the result of a massive effort involving thousands of workers, and cost over one hundred lives. The dam was controversially named in honor of President Herbert Hoover.

Since about 1900, the Black Canyon and nearby Boulder Canyon had been investigated for their potential to support a dam that would control floods, provide irrigation water and produce hydroelectric power. In 1928, Congress authorized the project. The winning bid to build the dam was submitted by a consortium called Six Companies, Inc., which began construction on the dam in early 1931. Such a large concrete structure had never been built before, and some of the techniques were unproven. The torrid summer weather and the lack of facilities near the site also presented difficulties. Nevertheless, Six Companies turned over the dam to the federal government on March 1, 1936, more than two years ahead of schedule.

Hoover Dam impounds Lake Mead, and is located near Boulder City, Nevada, a municipality originally constructed for workers on the construction project, about 25 mi (40 km) southeast of Las Vegas, Nevada. The dam's generators provide power for public and private utilities in Nevada, Arizona, and California. Hoover Dam is a major tourist attraction; nearly a million people tour the dam each year. Heavily travelled U.S. 93 ran along the dam's crest until October 2010, when the Hoover Dam Bypass opened.

USA - Nevada - Las Vegas

Welcome to fabulous Las Vegas, Nevada.

This is from Wikipedia : Las Vegas is the most populous city in Nevada, United States, the seat of Clark County, and an internationally renowned major resort city for gambling, shopping, and fine dining. Las Vegas, which bills itself as The Entertainment Capital of the World, is famous for its casino resorts and associated entertainment. A growing retirement and family city, it is the 28th-most populous city in the United States, with an estimated population by the U.S. Census Bureau of 583,756 as of 2010. The 2010 population estimate of the Las Vegas metropolitan area was 1,951,269.

Established in 1905, Las Vegas officially became a city in 1911. At the close of the 20th century, Las Vegas was the most populous American city founded in that century (a distinction held by Chicago in the 19th century). The city's tolerance for various forms of adult entertainment earned it the title of Sin City, and this image has made Las Vegas a popular setting for films and television programs. There are numerous outdoor lighting displays on Fremont Street, as well as elsewhere in the city.

The name Las Vegas is often applied to unincorporated areas that surround the city, especially the resort areas on and near the Las Vegas Strip. The 4.2 mi (6.8 km) stretch of Las Vegas Boulevard known as the Strip is mainly in the unincorporated communities of Paradise, Winchester, and Enterprise.

SIERRA NEVADA
Every summer, the Sierra Nevada is host to an abundance of varied flora. Pictured here, the bright Monkey Flower blankets the San Joaquin Ridge, near Mammoth Lakes, California.

This is from Wikipedia : The Sierra Nevada (Spanish: [ˈsjera neˈβaða], snowy mountain range) is a mountain range in the U.S. states of California and Nevada, between the California Central Valley and the Basin and Range Province. The Sierra run 400 miles (640 km) north-to-south, and are approximately 70 miles (110 km) across east-to-west. Notable Sierra features include Lake Tahoe, the largest alpine lake in North America; Mount Whitney at 14,505 feet (4,421 m), the highest point in the contiguous United States; and Yosemite Valley sculpted by glaciers out of 100-million-year-old granite. The Sierra is home to three parks, 20 wilderness areas, and a national monument. These areas include Yosemite and Sequoia, and Kings Canyon National Parks.

The character of the range is shaped by its geology and ecology. More than 100 million years ago, granite formed deep underground. The range started to uplift 4 million years ago, and erosion by glaciers exposed the granite and formed the light-colored mountains and cliffs that make up the range. The uplift caused a wide range of elevations and climates in the Sierra, which are reflected by the presence of five life zones.

The Sierra Nevada was home to several Native American tribes. The range was first sighted by Europeans in 1542, and then explored between 1844 and 1912.
