Grand Canyon(South Dim)

Las vegas - Hoover Dam - Grand Canyon - Las Vegas

Today the highlight of the day is to Grand Canyon, there was a choice of either South Rim or West Dim Skywalk. At first, there were two groups. But when the guide briefed the tour members on the differences, all tour members decided to go South Rim only. South Rim is more beautiful than West Rim, but without skywalk.

Hoover Dam
The Hoover Dam is located on the Nevada/Arizona border right outside of Boulder City, Nevada. Named one of the top 10 construction achievements of the 20th century, construction on the dam began in 1930 and was completed in less than five years. It is free to drive across the dam, though heightened security measures mean that some vehicles are subject to search and there is the potential to sit in heavy traffic while you wait to cross. If you prefer, you can also park and walk out across the dam. To learn more about the construction and history of the dam, you can pay to take a tour, which is well worth the time and money, but you can enjoy this attraction free of charge as well.

But when we reached the place, there are construction again to extend/expand the dam.



The Grand Canyon

The Grand Canyon is a UNESCO World Heritage Site that is located entirely in northern Arizona and is one of the great tourist attractions in the United States. The massive canyon encompasses several distinct areas, most famous of which is Grand Canyon National Park, a United States National Park. The national park is itself divided into two main areas: the remote North Rim and the more accessible (and therefore more crowded) South Rim. In addition, the southwestern end of the canyon is located within the borders of two Indian reservations: the Havasupai Indian Reservation and the Hualapai Indian Reservation (also known as Grand Canyon West). All of the sections of the canyon offer amenities for visitors, but the national park, and in particular the South Rim, is by far the most popular destination and the best equipped to handle the millions of yearly visitors.

The Grand Canyon is a massive canyon carved over several million years by the Colorado River. Grand Canyon National Park boasts an elevation change of nearly 7,000 feet (2130 m) from Point Imperial (at nearly 9,000 feet or 2740 m) to the banks of Lake Mead (at just over 2,000 feet or 610 m). The canyon itself is, from rim to river over a mile (1610 m) deep. In spots the rock layers exposed in the canyon display over two billion years of geologic history.

Grand Canyon National Park is one of the United States' oldest national parks and is located in Arizona. Within the park lies the Grand Canyon, a gorge of the Colorado River, considered to be one of the major natural wonders of the world. The park covers 1,902 mi2 (4927 km2) of unincorporated area in Coconino County and Mohave County.

Most visitors to the park come to the South Rim, arriving on Arizona State Route 64. The Highway enters the park through the South Entrance, near Tusayan, Arizona, and heads eastward, leaving the park through the East Entrance. All park accommodations are operated by the Xanterra corporation. Park headquarters are at Grand Canyon Village, a short distance from the South Entrance, being also the center of the most popular viewpoints. Some thirty miles of the South Rim are accessible by road. A much smaller venue for tourists is found on the North Rim, accessed by Arizona State Route 67. There is no road connection between the two within Arizona except via the Navajo Bridge, near Page, Arizona, entailing a five-hour drive. Otherwise, the two rims of the Canyon are connected via Las Vegas, Nevada, and the Hoover Dam.

The rest of the Grand Canyon is extremely rugged and remote, although many places are accessible by pack trail and backcountry roads.

The area around the Grand Canyon became a national monument on January 11, 1908, and was designated national park on February 26, 1919. The creation of the park was an early success of the environmental conservation movement; its National Park status may have helped thwart proposals to dam the Colorado River within its boundaries. (Lack of this fame may have enabled Glen Canyon Dam to be built upriver, flooding Glen Canyon and creating Lake Powell.) In 1979, UNESCO declared it as a World Heritage Site.

The Grand Canyon itself, including its extensive system of tributary canyons, is valued for the combination of large size, depth, and the exposed layering of colorful rocks dating back to Precambrian times. It was created through the incision of the Colorado River and its tributaries after the Colorado Plateau was uplifted and the Colorado River system developed along its present path.

The Grand Canyon is a steep-sided canyon carved by the Colorado River in the United States in the state of Arizona. It is largely contained within the Grand Canyon National Park, one of the first national parks in the United States. President Theodore Roosevelt was a major proponent of preservation of the Grand Canyon area, and visited it on numerous occasions to hunt and enjoy the scenery.

The Grand Canyon is 277 miles (446 km) long, up to 18 miles (29 km) wide and attains a depth of over a mile (1.83 km) (6000 feet). Nearly two billion years of the Earth's geological history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted. While the specific geologic processes and timing that formed the Grand Canyon are the subject of debate by geologists, recent evidence suggests the Colorado River established its course through the canyon at least 17 million years ago. Since that time, the Colorado River continued to erode and form the canyon to the point we see it at today.

Before European immigration, the area was inhabited by Native Americans who built settlements within the canyon and its many caves. The Pueblo people considered the Grand Canyon ("Ongtupqa" in Hopi language) a holy site and made pilgrimages to it. The first European known to have viewed the Grand Canyon was García López de Cárdenas from Spain, who arrived in 1540.
