The Three Gorges are in China.
They sit along the Yangtze River. The river flows through three big gaps in the mountains. These gaps are called gorges.
The mountains are very tall. They have steep cliffs. Some parts are narrow. Other parts are wide.
People visit to see the view. You can see it from a boat.
A big dam was built there. The dam makes the river much wider. This helps big ships move through.
It is a very famous place.
The Three Gorges are in China. They sit along the Yangtze River. This river flows through three big gaps in the mountains. These gaps are called gorges. The three gorges are named Qutang, Wu, and Xiling.
The mountains are very tall and steep. Some parts of the gorges are narrow. Other parts are wide. This happens because of the rocks. Hard limestone makes narrow gaps. Softer rocks like sandstone make wide valleys. People say you can hear monkeys howling in the hills.
A very big dam was built at Yichang. This is the Three Gorges Dam. It was finished in 2008. The dam holds back a huge amount of water. This created a large reservoir. The river is now much wider and deeper. This helps very large ships move through the area. The water level has changed the view. The mountains now look lower next to the wide river. Many old towns and sites are now under the water. Some places, like Shibaozhai, were saved with special walls.
The Three Gorges are three beautiful gaps in the mountains. They sit along the middle part of the Yangtze River. These gaps are in the People's Republic of China. The Three Gorges include the Qutang, Wu, and Xiling gorges. They stretch from Baidicheng in Chongqing to Yichang in Hubei Province.
This area is very famous for its scenery. It is also a very important place for Chinese history and culture.
Nature shaped these valleys in different ways. Some parts of the gorges are very narrow. Other parts are much wider. This happens because of the different types of rock. Hard limestone makes narrow gaps because it resists erosion. Water flows through cracks in the limestone and wears it away. This creates steep cliffs. Softer rocks like sandstone make wide valleys because they wear away more easily.
People have admired these views for hundreds of years. Long ago, writers described the tall mountains and deep water. The mountains are so close together that they block the sun. You might only see the sun at noon. In the summer, the water rises very high. This can make it hard for boats to move. Some people say you can hear monkeys howling from the peaks.
Moving through the gorges was a hard job in the past. For a long time, people had to pull boats by hand. It was a dangerous path with swift currents. In the 1900s, people began to talk about building a dam. The Three Gorges Dam was finally built at Sandouping in Yichang. Construction on the dam finished by the end of 2008. A special ship lift was also finished in 2015.
The big dam changed the whole region. It created a huge reservoir of water. Now the river is much wider and deeper. This helps very large ships carry cargo through the area. However, the high water also covered many old towns. Some special sites, like the Baiheliang markers, are now underwater. Other places, like the Shibaozhai fortress, were saved with special walls. The mountains now look lower because the river is so wide.
The Three Gorges are three adjacent and sequential river valleys located along the middle reaches of the Yangtze River. They are situated in the hinterland of the People's Republic of China. These gorges are part of a larger region known for its dramatic scenery and deep cultural history. The sequence begins with the Qutang Gorge, followed by the Wu Gorge, and ends with the Xiling Gorge.
The area spans from Baidicheng in Chongqing to Nanjin Pass in Yichang City, Hubei Province. This region includes several counties, such as Fengjie and Wushan in Chongqing, and Badong and Zigui in Hubei.
Geological forces shaped these valleys over millions of years. Geologists believe mountain folding occurred during the Yanshanian movement about 70 million years ago. This movement involved the Wu Mountains in the west of Hubei and east of Sichuan Province. As the Earth's crust rose, the Yangtze River's erosion became more intense. This process carved the gorges through the landscape. The river flows from southwest to northeast and then turns toward the east. The terrain gradually lowers from the south toward the north.
The specific shape of each gorge depends on the local lithology, which is the study of rock types. In areas with limestone, the valleys are often very narrow. Limestone is a hard rock that resists erosion. However, water can flow through deep vertical fractures in the stone. As the water undercuts the limestone, parts of the rock fall into the river. This creates precipitous, or very steep, cliffs. In contrast, areas with sandstone and shale have wider valleys. These rocks are softer and have less resistance to the erosive power of the water.
For centuries, people have admired the natural grandeur of this region. During the Northern Wei dynasty, the writer Li Daoyuan described the overlapping mountains. He noted that the cliffs are so close that they shield the area from the sky. In these valleys, the sun may only be seen at noon. The poet Li Bai also wrote about the scenery. He described the sound of monkeys howling from the mountain peaks. The Wu Gorge is often thought to be the longest by local fishers because of these echoes.
Navigating the Three Gorges was historically difficult and dangerous. In the 1700s, much of the cargo was manually towed upstream by workers. The currents were swift, and agriculture on the slopes caused further erosion. To improve safety, various projects were started in the 1800s. These included carving towpaths and removing dangerous rocks. Even after motorized boats were introduced, manual labor continued until the 1970s. Eventually, the need for hydroelectric power led to massive changes in the region.
Plans for a large dam were discussed for many years. In 1919, Sun Yat-sen proposed the concept of damming the gorges. In 1944, an American engineer named John L. Savage investigated the site and wrote an enthusiastic report. However, the project faced many delays due to the Chinese Civil War and political debates. Finally, the National People's Congress passed a resolution for the dam in 1992. The Three Gorges Dam was built at Sandouping in Yichang. The reservoir dam was completed on May 20, 2006, and the project finished by the end of 2008.
The dam has transformed the local ecology and the way people live. The creation of the Three Gorges Reservoir caused the mass relocation of many towns and villages. The higher water level has made the river wider and deeper. This allows much larger ships and container barges to travel through the gorges. While the river is wider, the mountains still tower above the water. The scenery has changed, but the dramatic cliffs remain a major attraction for river cruises.
This transformation also impacted many historical and cultural sites. Some sites, like the Baiheliang hydrographic marks, were submerged by the rising water. These marks include 165 paragraphs of inscriptions used to forecast agricultural outcomes. To protect this history, the Baiheliang Underwater Museum was created. Other sites required special protection, such as the Shibaozhai fortress. A dam was built specifically around this structure to save it. The Zhang Fei Temple was also affected, though many of its stone inscriptions and woodcarvings were saved.
