The First Descent of the Grand Canyon

John Wesley Powell is one of the most important explorers in the American history, first crossing the Grand Canyon along the Colorado River and is one of America's greatest adventure stories. He is not as famous as other explorers, but his travel and its contribution to the American history are important. It is not for self-worship, gold or land acquisition, but for the spirit of discovery. From curiosity and appreciation. The nature and the west side are indigenous people.

Before explaining how to form and form the Grand Canyon, it is important to understand the sculptural location and the geological features. The Grand Canyon is located in the northern part of Arizona State and eroded by the southern edge of the Colorado Plateau. Through the sandstone, limestone, shale sediments and the infrastructure of most metamorphic schist and igneous granitic rocks, the Grand Canyon proves the erosiveness of water. But how are these rock formations formed? As shown in Figure 1, they can be divided into three groups. Most creative geologists believe that crystalline foundation was set on the third day of the creation week. The sedimentary layer before the tilted flooding is 14,000 feet (4,260 meters) thick, but it is exposed only to the east canyon and other areas.

Are there any other places where you can walk the Sky Trail? Grand Canyon Skywalk is located in Hualapai Indian Reservation of Grand Canyon West. This clever structure lies 4000 feet above the ground of the canyon. It was opened to visitors in March 2007. During the opening ceremony, astronaut Buzz Aldrin performed a historic "first walk". Grand Canyon has a long history. Researchers have found over 4,800 ruins carrying echoes of ancient Indian tribes. Evidence from artifacts shows that humans lived in the Grand Canyon 4000 years ago and experienced 6500 years ago.

For thousands of years, the area lived in the valley and the native American who built the village in its many caves. The people of Pueblo believe that the Grand Canyon is a sacred place and a pilgrimage to the pilgrimage. The first European who saw the Grand Canyon was Spain 's Garcia Lopes de Cardenas which arrived in 1540. The Grand Canyon is the valley of the Colorado Plateau that exposes the rising Proterozoic and Paleozoic strata and is also part of the topography of the Colorado plateau. It is not the deepest valley in the world (deeper in the Karigandaki Gorge in Nepal). However, the Grand Canyon is known for its visually overwhelming size and complicated colorful landscape. Geologically, the ancient rock sequence is well preserved and is important as it is exposed on the walls of a canyon. These rock formations record the earliest geological history of the North American continent.
