Three Gorges
The Three Gorges are a series of three sequential gorges along the middle reaches of the Yangtze River in China, renowned for their dramatic scenery and historical significance. Formed over millions of years by river erosion and tectonic uplift, these gorges have been a vital waterway and a source of inspiration for art and literature for centuries. Their landscape has been significantly altered by the construction of the Three Gorges Dam, which has impacted the region's ecology and submerged numerous cultural sites.
Key Facts
- ›The three Gorges comprise the Qutang, Wu, and Xiling gorges, spanning a total of 311 km (193 miles).
- ›Their formation is attributed to mountain folding and intensified river erosion due to crustal uplift, with significant geological activity around 70 million years ago.
- ›The gorges are characterized by narrow valleys in limestone regions and wider valleys in softer sandstone and shale areas.
- ›Historically, they were a crucial but dangerous waterway connecting Sichuan and Guizhou to eastern China, with navigation challenges mitigated by ancient engineering efforts.
- ›The region is rich in historical and cultural sites, many of which have been submerged or relocated due to the three Gorges Dam project.
- ›The scenery has been celebrated in Chinese art and literature for over a thousand years, with notable descriptions from the Northern Wei and Eastern Jin dynasties.

About Three Gorges
The Three Gorges
The Three Gorges are a series of three adjacent and sequential gorges located along the middle reaches of the Yangtze River in the People's Republic of China. These gorges, known for their dramatic scenery and historical significance, comprise the Qutang Gorge, followed by the Wu Gorge, and finally the Xiling Gorge. They span a total length of approximately 311 kilometers (193 miles), beginning at Baidicheng in Chongqing Municipality and extending to Nanjin Pass in Hubei Province.
Geological Formation and Characteristics
The formation of the Three Gorges is attributed to a combination of tectonic uplift and the erosive power of the Yangtze River. Around 70 million years ago, mountain folding in eastern Sichuan Province and western Hubei Province, including the Wu Mountains, occurred as a result of the Yanshanian movement. As the Earth's crust in the region continued to rise, the river's erosion intensified, carving out the dramatic gorges. The geological composition of the area influences the gorge's structure; hard limestone resists erosion, leading to narrow valleys and precipitous cliffs, while softer sandstone and shale allow for wider valleys. Water's ability to flow along deep vertical fractures in limestone also contributes to the formation of steep cliff faces.
Scenic Grandeur and Cultural Significance
The natural beauty of the Three Gorges has been a source of inspiration for artists and writers for centuries. Descriptions dating back to the Northern Wei dynasty (386–534 AD) and the Eastern Jin dynasty highlight the seamless mountains, elegant peaks, and unique rock formations that characterize the landscape. The gorges were famously depicted in classical Chinese poetry, such as Li Bai's "Setting out from Baidicheng," which captures the swiftness of passage and the surrounding natural splendor. Beyond their aesthetic appeal, the Three Gorges region holds significant historical and cultural importance, serving as a crucial waterway and a repository of numerous settlements and archaeological sites.
Impact of Modern Development
In the 20th and 21st centuries, the Three Gorges have become the site of a monumental engineering project: the Three Gorges Dam. Initiated in 1994 and largely completed by 2008, the dam has profoundly altered the region's ecology and landscape. The creation of the Three Gorges Reservoir has raised the water level significantly, changing the appearance of the gorges and leading to the submersion of many historical towns, villages, and cultural relics. Despite these changes, the gorges continue to offer impressive views of towering cliffs, and the increased water depth has facilitated larger vessels, boosting river traffic and tourism. Efforts have been made to preserve or relocate significant cultural sites, such as the Baiheliang hydrographic mark and the Shibaozhai fortress, to mitigate the impact of the dam's construction.

Frequently Asked Questions
How were the Three Gorges formed?
The Three Gorges were primarily formed by the erosive power of the Yangtze River, intensified by tectonic uplift and mountain folding in the region. The geological processes, including the Yanshanian movement around 70 million years ago, led to crustal rise, which increased the river's erosive capacity and carved the gorges.
What are the main geological characteristics of the Three Gorges?
The valleys within the Three Gorges vary in width due to differing rock resistances. Hard limestone areas result in narrow gorges with precipitous cliffs, while softer sandstone and shale formations lead to broader valleys. Water erosion along deep vertical fractures in limestone also contributes to the steep cliff formations.
What are some notable scenic features within the Three Gorges?
The Three Gorges are known for their dramatic cliffs, elegant peaks, and unique rock structures. Scenic spots include the Kuimen, the western entrance to the gorges, and various formations within the Wu and Xiling gorges, such as Fairy Peak and Military Book and Sword Gorge.
How has the Three Gorges Dam affected the region?
The Three Gorges Dam has significantly altered the region's ecology and landscape. The reservoir has raised the water level, making the river wider and causing many historical settlements and archaeological sites to be submerged. While the dam has increased river traffic and navigation, it has also led to the mass relocation of towns and villages.
Are there any significant cultural or historical sites within the Three Gorges?
Yes, the Three Gorges region is historically and culturally important. Sites such as the Baiheliang hydrographic mark, Shibaozhai fortress, and the Zhang Fei Temple have been preserved or relocated due to the dam project, though many other relics were lost to the reservoir.
What is the current state of tourism in the Three Gorges?
Riverboat companies operating on the Three Gorges have seen an increase in demand for river cruises, partly due to the larger ships that can now navigate the wider and deeper river. The gorges continue to offer views of surrounding cliffs, attracting tourists interested in both natural scenery and the human-made transformations of the area.

Qutang Gorge
The Qutang Gorge is the shortest and narrowest of China's Three Gorges, carved by the Yangtze River between the Chijia and Baiyan Mountains. Renowned for its spectacular, dramatic scenery, it is often considered the most beautiful of the three gorges due to the combination of high mountains and tight passages. Historically, it served as a crucial passage for boat haulers via ancient pathways, and it contains numerous significant historical and cultural sites, some of which have been impacted by the Three Gorges Dam.
Wu Gorge
Wu Gorge is the second of the Three Gorges on the Yangtze River in China, stretching 45 kilometers from Wushan to Guandukou. Renowned for its dramatic scenery and the legendary Goddess Peak within the Wu Mountains, it has been a significant landmark since at least the Three Kingdoms period. The gorge is a popular tourist destination, offering a glimpse into China's natural beauty and historical significance.
Xiling Gorge
Xiling Gorge is the easternmost and largest of the Three Gorges on the Yangtze River in Hubei province, China. Named after Mt. Xiling, it was historically known as the most dangerous gorge to navigate due to treacherous whirlpools and strong rapids. The construction of the Three Gorges Dam and Gezhouba Dam significantly altered its hydraulic characteristics.
