Grand Canyon is one of the greatest natural wonders on earth. Stand on the edge and admire the stunning magnitude and beauty of this unforgettable experience. The length of the canyon is 443 km and its width ranges from 200 m to 29 km. Maximum depth of the canyon (in the granite gorge) is 1.6 km.

Grand Canyon cut out from the plateau found located in the northwestern part of Arizona, who was once the bottom of an ancient ocean. Two rivers, ancient and Hualapo Colorado, broke through the plateau and merged to form present-day Colorado River.

At the same time, about 60 million years ago, as a result of crustal movements plateau shifted upward. Flowing rapidly (at speeds up to 32 km per hour.) Colorado River canyon sides rinsed, boring deep trough.

The layers of rock canyon is recorded geological history of this region. The youngest rocks on the top count 225 million years. Tena bottom – over 2 billion years. All the geological layers contain fossils of marine animals, trees and dinosaurs.

Grand Canyon – the turn of the Colorado River in Arizona in the U.S. by the Colorado Plateau, consisting mainly of slate Yishnu, as well as slate, limestone, sandstone and granite intrusions. The canyon is full of geological cross-section of the Proterozoic (Precambrian era) after the Triassic (Mesozoic Era). Each series of rock layers has a different hue. Sedimentary rocks rich in fossils of the canyon, from primitive algae to trees, sea shells from the remains of dinosaurs. Canyon formation time is estimated at about 10 million years. Canyon began to emerge first in the western part of the current course, 17 million years ago, while the eastern end amounted to 5-6 million years ago. In the next million years, took the plunge indentation and deepening of the river canyon, while preserving its length. His “architect” was the Colorado River, formed the canyon as the Colorado Plateau to rise. Prior to the construction in 1963, Glen Canyon dam river canyon carried by 500,000 tonnes of sludge per day and is currently only 80,000 tons. At present, the Grand Canyon is 349 km long and the deepest site (Granite Gorge – Granite Gorge) in 2133 m depth. The width varies from about 800 m (under the viewpoint Toroweap the North Rim – North Rim) to 29 km at its widest point. This is the biggest breakthrough of the river in the world (though not the deepest). The deepest canyon on earth is Cotahuasi canyon in Peru. The largest and deepest canyon in Europe is a breakthrough of the river Tara in Montenegro.
This area is a National Park – Grand Canyon National Park.

Skywalk observation platform

March 28, 2007 has been the grand opening of the glass bridge over the western part of the Grand Canyon (Grand Canyon West). This “highest balcony” in the world. It is situated at an altitude of 1219 meters above the ground. The opening attraction for the audience held a few days later. For 29.5 USD / person (03.2009) (and approximately 30USD for purchase tourist route) interested have the opportunity to enjoy the opening abyss beneath them the Grand Canyon, separated from her only a transparent glass pane. Glass Skywalk observation deck is considered a miracle of engineering, cost $ 30 million and has a horseshoe-shaped projecting more than 20 meters from the edge of a cliff that drops straight down to a depth of 1220 meters. Located 144 km in a straight line to the west of Grand Canyon National Park, visited every year by 4.1 million tourists in areas Hualapai Indian Reservation in Arizona. The platform must not take pictures (cameras and mobile phones are transferred to the deposit). Photos are executed only by persons authorized and available for a fee.

Skywalk was designed by architects MRJ Architects and their design solution address the business Lochsa Engineering. Glass, which brought a horseshoe glass taken from the German plants, specializing in the manufacture of structural glass for unique building projects worldwide. According to architect Mark Johnson, Skywalk at the same time able to carry 120 people and can withstand winds in the Canyon at 160 km per hour. The platform also features a cushioning system that did not fell the vibrations caused by the displacement of people.
