Does anyone know about the Grand Canyon of Colorado?

The Grand Canyon is a world-famous natural wonder located on the Kaibab Plateau in northwest Arizona in the western United States. The Grand Canyon is 446 kilometers long, with an average width of 16 kilometers and a maximum depth of 1,740 meters. The average valley depth is 1,600 meters and the total area is 2,724 square kilometers. Because the Colorado River flows through it, it is also called the Grand Canyon. It is one of the natural heritage sites selected by UNESCO to be protected.

Colorado, the Grand Canyon, Grand Canvon, Colorado Grand Canyon, Grand Canyon Colorado) The Grand Canyon is a masterpiece of the Colorado River. This river originates in the Rocky Mountains of Colorado, flows through Utah, Arizona, and enters the sea from the Gulf of California in California. The total length is 2320 kilometers. "Colorado" means "Red River" in Spanish. This is because the river often appears red due to the large amount of sediment carried in it, hence the name. The Colorado River has been eroding for a long time, rushing forward day and night, sometimes cutting through mountains and sometimes giving way to flow back. It has carved out 19 canyons such as Black Canyon, Canyonlands, Glen Canyon, and Bruce Canyon in the upper reaches of the main stream and tributaries. , and when it finally flows through the rocky Kaibab Plateau in Arizona, there is an astonishing stroke, forming this grand canyon wonder, and becoming the "King of Canyons" among all the canyons in this water system. The shape of the Grand Canyon is extremely irregular, running roughly east-west and winding like an unruly python, prostrate on the Kaibab Plateau. Its width is between 6 kilometers and 25 kilometers. The two sides of the canyon are high in the north and low in the south. The average valley depth is 1,600 meters and the width of the valley bottom is 762 meters. The Colorado River surges forward at the bottom of the valley, forming a spectacular scene of two mountains standing on one side and one flowing in the water. Its majestic landform, vast spirit, breathtaking demeanor, and strange scenery are unparalleled in the world. When U.S. President Theodore Roosevelt visited here in 1903, he sighed and said: "The Grand Canyon fills me with awe. It is incomparable, indescribable, and unique in this vast world." Some people say that in The only natural landscape from space that can be seen with the naked eye is the Grand Canyon. The width of the valley floor of the Grand Canyon is between 200 and 29,000 meters. As early as 5,000 years ago, indigenous American Indians lived here. The rocks of the Grand Canyon are a geological picture, reflecting different geological periods. They change different colors under the sunlight. The magical colors have attracted the attention of countless tourists from all over the world. Because people can observe strata from various periods from the Paleozoic to the Cenozoic from the valley wall, it is known as a "living geological textbook."

The Colorado Plateau is a typical "table-shaped plateau", also known as "table mountain", which is a mountain with a flat top and steep sides. This topography was formed due to erosion (undercutting and exfoliation). During erosion, the harder rock formations in the plateau form a protective cap in the areas between river valleys where erosion is active. The result is a platform-shaped mountain or a fortress-shaped hill. The Colorado Plateau is a stable block of North American ancient continental platform extending into the Cordillera region. Due to its relative stability, the surface fluctuations are minimal, and the base of Precambrian crystalline rocks is covered with thick sediments of various geological periods. , its horizontal layers are clear, the rock formations have different tones, and contain representative biological fossils from various geological periods. Rock layers with different lithologies and colors are carved by external forces into a variety of strange peaks and rocks, such as Table Mountain

and cliff pillars. As the weather changes, the water, light, and mountains change, and the natural wonders become spectacular. The climate and landscape are very different between the two walls of the canyon and the valley bottom. The south wall is dry and warm, with few plants; the north wall is higher than the south wall, with a cold and humid climate and green trees; the valley bottom is dry and hot, presenting a desert landscape. The Colorado River meanders at the bottom of the valley with deep twists and turns. The river bed ratio of the entire Grand Canyon is reduced to 150 centimeters per kilometer, which is 25 times that of the Mississippi River. Among them, 50% of the drop is very concentrated, which creates a landscape of rushing rivers in some parts of the canyon. Because of this, sailing and rafting along the canyon becomes a fascinating adventure activity.

It is said that the Grand Canyon was discovered in 1869 by an expedition team led by John Wesley Powell, a major of the American independent artillery. When U.S. President Theodore Roosevelt visited here in 1903, he exclaimed: "The Grand Canyon fills me with awe. It is incomparable, indescribable, and unique in this vast world." In 1919, Wilson The president designated the Grand Canyon area as the "Grand Canyon National Park" and it was included in the World Heritage List in 1980. The rocks in the Grand Canyon are mostly red. From the bottom to the top of the valley, there are rock formations from the Cambrian to the Cenozoic Era. The layers are clear and the colors are different. They also contain representative biological fossils of various geological ages. They are also known as "living... Geological History Textbook”.

The Grand Canyon starts from the Little Colorado River. It is the longest, widest and deepest of the 19 major canyons formed by the intense erosion of the 2,190-kilometer-long Colorado River. It is also the most famous one, the Grand Canyon of the Colorado

Both sides of the Grand Canyon are covered with huge red rock faults. Nature has used uncanny creativity to carve out rugged rock formations and mountains, sandwiching a huge bottomless valley, showing incomparable vitality and magnificence. What's even more peculiar is that although the soil here is mostly brown, when it is bathed in sunlight, depending on the intensity of the sun's rays, the color of the rocks will sometimes be dark blue, sometimes brown, and sometimes again. It is red, always confusing and ever-changing, highlighting the beauty and mystery of nature. At this time, the Grand Canyon is as colorful, vast and psychedelic as a fairyland, and the charming scenery is unforgettable. The color and structure of the canyon, especially its majestic charm, cannot be imitated by any sculptor or painter. The horizontal rock layers on the canyon walls are clear and distinct. These are geological sediments hundreds of millions of years ago. Just like the annual rings of trees, they provide sufficient basis for people to understand geological changes. In addition to its majestic aspect, the Grand Canyon also has many twists and turns; the two cliffs stand thousands of feet high, and the scenery between them is a line of blue sky. While it is amazing, it will inevitably make you feel as if you are just ahead. There are brave men who are in charge. Other caves and rock valleys formed by the impact of water flow have various shapes and are as red as fire. Every rock seems to be a beautiful painting. Being in them is like entering a fairyland. In the cinema of Grand Canyon National Park, there is the world's largest screen, which interprets the history and changes of the Grand Canyon. Hundreds of millions of years ago, like the Himalayas, this place was once a vast ocean, and the orogeny caused it to rise. However, due to the softness of the stone, after millions of years of erosion by the rapid Colorado River, the rock walls on both sides were cut by friction into the world-famous Grand Canyon that is today nearly 400 kilometers long, about 20 kilometers wide, and with an average depth of 1,500 meters. Since John Wesley Powell first rafted the Grand Canyon in 1869, countless American explorers have followed his footsteps in the Grand Canyon to challenge dangerous shoals and fight rapids over the past 100 years, interpreting an American spirit here. The Grand Canyon in the United States is one of the largest canyons in the world and one of the seven wonders of nature on earth. Many people who have visited this place around the world lamented: Only the famous Grand Canyon in the United States is A true symbol. The Grand Canyon has a total area of ??nearly 3,000 square kilometers. It is impossible for anyone to see the entire Grand Canyon at a glance. Only from a high altitude is it possible to fully appreciate this crack in the earth. Those who are truly immersed in the experience can only appreciate part of the Grand Canyon from the south or north rim of the canyon. This is in line with the saying "if you don't know the true face of Mount Lu, you just live in this mountain". Grand Canyon

After visiting the Grand Canyon in 1890, American writer John Muir wrote: "No matter how many roads you travel and how many famous mountains and rivers you see, you will always feel that the Grand Canyon can only exist in Another world, another planet.” This is true. The Grand Canyon is a natural miracle. Only when you get here will you realize your own insignificance, or the insignificance of human beings in front of nature. Standing at the edge of the canyon, you will be surprised how this land has been opened up in front of you by uncanny workmanship, revealing the colorful cross-sections inside. The abyss under the cliff is unfathomable. Although it is surrounded by guardrails, the magic from the abyss is still frightening and makes people dare not face it. You will suspect that you have arrived at the gate of hell, and Pluto is smiling and looking at his next prey. Or you may feel like you've reached the end of the world and are alone, leaving the world behind. It brings you an indescribable shock. The so-called human history and the passage of time seem to be reduced to a grain of sand in front of this gap. Many people cannot resist the temptation to find out more and choose to ride a mule or horseback to the bottom of the valley. If you really go down to the bottom of the valley, you will find that this is another world. In the depths of "hell", one does not necessarily have to endure endless pain. What you experience is nothing more than the life of the Western cowboys galloping through the wilderness. The scene of cowboys riding horses and carrying guns, often seen in American western movies, galloping on the barren red land is a portrayal of the Grand Canyon area at that time. Many western movies are still shot here because the western style here is the purest. In 2002, field reporters and editors from the authoritative National Geographic magazine conducted a selection: rafting the entire Grand Canyon along the Colorado River in a rubber raft ranked among the 100 most exciting and challenging adventure activities in the United States. Top of the list. Since the Grand Canyon is not only the most exciting and challenging adventure activity, but also a magnificent tourist experience, being able to participate in activities with such unparalleled otherworldly charm has led to countless people around the world dreaming of it and waiting in line for 18 Years later, you will be able to experience this enjoyment and be proud and honored! For hundreds of millions of years, the roaring Colorado River has cut this shocking miracle, the Grand Canyon, from the Campaboo Plateau in northern Arizona in the western United States. As long as you climb up and look far away, you can clearly see the plateau as flat as a tabletop. A big crack in the river is the imprint of the Colorado River on this vast land.

The Grand Canyon offers visitors an unparalleled opportunity to admire the spectacular swaths of ancient canyon from the edge of steep, clustered cliffs. It is not the deepest canyon in the world, but it is famous for its extraordinary surface and intricate, colorful landscape. From a geological point of view, it is very valuable because the huge stone blocks preserved from ancient times exposed on the canyon walls are beautiful because of their hardness and roughness. These stone layers silently record the early geological formation and development of the North American continent. It is, of course, the most fascinating place on earth to study wind erosion. In the Grand Canyon, there are 75 species of mammals, 50 species of amphibians and reptiles, 25 species of fish and more than 300 species of birds. The entire national park is home to many animals. Caribou are one of the most common mammals in the canyon and can be commonly observed from the cliff edges. Desert argali sheep live on the steep cliffs deep in the canyon and are not easily found on the usual tourist routes. Bobcats and mountain dogs of medium or smaller size live in an unstable range from the edge of cliffs to rivers. There are also a small number of mountain lions in national parks. Small mammals include raccoons, beavers, chipmunks, gophers, and several different species of squirrels, rabbits, and mice. Amphibians and reptiles include a wide variety of lizards, snakes (including the endemic Grand Canyon pink rattlesnake), turtles, frogs, toads and salamanders. Hundreds of different species of birds and countless insects and arthropods (spiders) live here.

The Grand Canyon: the largest and most spectacular erosional landform in the world

The Grand Canyon is about 446 kilometers long, with widths ranging from 6 kilometers to dozens of kilometers, and the deepest point can reach 1,824 meters. , nearly 2 kilometers, the valley river surface is 1,740 meters above sea level, and the highest altitude of the valley bank can reach more than 3,000 meters. For hundreds of millions of years, the roaring Colorado River has cut this shocking miracle from the Kaibab Plateau. Whether you are on the south bank or the north bank, looking from a high distance, you can clearly see a big crack on the tabletop plateau, which is the imprint of the Colorado River on this wild land. It’s not the deepest canyon in the world, but it’s notable for its sheer size and richness. It attracts the world's attention and is the most important reason why it is listed as a World Natural Heritage. It also lies in its geological significance: the well-preserved and fully exposed rock formations record almost the entire geological history of the early North American continent. It records Paleozoic rocks from 5.5 to 2.5 million years ago. After that, they were either not deposited or have weathered. The formation of the canyon is much later than its rocks (about 50,000-60,000 years ago) and is much more complicated. It is mainly the erosion of the Co River, and the erosion effects of rainfall, ice and snow melt are almost equally important. The peculiar shape is mainly due to the different speeds of erosion on rocks with different textures. The rich colors of the canyon are caused by the small amounts of various minerals contained. Rocks rich in iron are red or reddish brown. Until the American Civil War, the Grand Canyon was little known. In 1869, John Wesley Powell, a Civil War veteran who loved science and exploration, went rafting for the first time. Animal husbandry began to develop in the Grand Canyon area in 1880. By 1890, it was still an alpine grassland, with 150,000 cattle and 250,000 sheep grazing here. But by the time the Grand Canyon Nature Reserve was established in 1906, most ranchers were forced to change careers. Because of overgrazing, the semi-arid grasslands with fragile ecological environment had turned into shrubs and deserts, making animal husbandry unsustainable and the industry gradually declining. dominant. By 1901, the railway was built to the south bank, which led to rapid development. It became a national park in 1919 (the U.S. National Park Service was established in 1916).

Rock Arch National Park

Approached the town of Moab on the plateau where Rock Arch National Park is located. After entering the door, turn and go uphill. The first group of strange rocks rushes in front of the car, followed by a huge group! They are all made of weathered red rock. They are continuous and naked, red and arousing visual impact, like castles, giant beasts, Ashima girls, churches, sails... This park is named after the concentration of natural stone arches. There are more than 2,000 rock arches with a span of more than 1 meter in the park, and there are also strange groups of stone pillars and stone piers scattered everywhere. The highway connects several scenic spots together, and the densely packed areas are full of beautiful scenery, making it dizzying to see. Walking next to the huge rock arch in the cool sun, walking through the dry trees, listening to the sound of the wind, I felt a real sense of solidity. The window area is where large rock arches gather, and several famous arches appear frequently on postcards. The Double Arch consists of two beautiful arches stacked next to each other. When viewed from the front, it looks like a chain, which is extremely elegant. Tourists were scurrying below, only to realize how high it was! A few miles away, Delicate Arch is an exquisitely isolated rock slope so famous that it is used as the image on Utah license plates. Walk a mile to see the Landscape Arch. It is one of the largest rock arches in the world, spanning 100 meters and 30 to 40 meters high. The top is only a few feet thin and may collapse at any time. The information said: "You are witnessing the sunset of a rock arch. The next time you visit, it may not exist." When I looked up again, I felt that it was not an exaggeration. The life of a rock arch begins when wind, frost, rain and snow create small pits on the mountain, then penetrate into holes, expand, and finally collapse into dust. New rock arches are born, old rock arches die, and time flows before your eyes. Making popular science knowledge vivid and interesting is a characteristic of North American natural scenic spots, and Rock Arch Park is no exception.

Some signboards ask visitors to face a certain landscape and boldly draw shapes and colors, saying that it was originally a mountain, but later it became a huge rock arch, and then Mother Nature flattened it. The story is accompanied by a diagram, with dotted and solid lines depicting hundreds of millions of years of history, and the landscape in front of us does support that story. This mountain and thick land have been eroded layer by layer! Yan Gong Park covers an area of ??only more than 200 square kilometers. It has always been known as a family park, which means that transportation and viewing are convenient, and it is suitable for family travel. The park attaches great importance to maintaining the natural ecology and does not build any commercial facilities, not even restaurants. There are only a few sagebrush growing on the vast Gobi Desert, which is also the highlight of the park. Hollywood once came to borrow a piece of treasure land, saying that it would invest 500 horses to film a fierce battle between Indians and federal cavalry, but the park collapsed and returned with two words: "No way." In fact, it is well known that the National Park System is strapped for cash, but the brainless park director still said: "I can't imagine letting them let 500 horses in to cause trouble!" This man's integrity made people look at Americans with admiration.
