Let us dive into the worlds of Hang Son Doong and uncover its wonders.
What is Hang Son Doong Cave?
Hang Son Doong Cave is located in Quang Binh Province, Vietnam, and is considered the largest cave in the world, extending over 5 kilometers (about 3 miles) and reaching a height of approximately 200 meters (660 feet). This cave is a unique natural phenomenon, featuring two groups of primitive forests, and is characterized by its stunning geological formations that have made it a destination for both researchers and tourists alike. This cave was formed due to the erosion of limestone over millions of years by river waters, a unique geological event that enhances the site’s importance in geological and environmental studies.
History of the Cave’s Discovery
The story of the discovery of Hang Son Doong Cave dates back to 1990 when Ho Khanh, a local resident, encountered an unexpected event while fishing. He felt a strong draft and heard the sound of a river inside the cave. However, he could not find the entrance again because of the dense vegetation surrounding the area. After several years, Ho Khanh was able to retrace his steps to lead a team of British explorers to the entrance of the cave in 2009. From there, the exciting journey of discoveries began. By that time, the team’s measurements proved that the cave was the largest ever recorded.
Geological Characteristics
Hang Son Doong Cave is famous for its massive size, with an estimated volume of about 38.5 million cubic meters, enough to accommodate around 15 pyramids of Giza. It contains supernatural formations such as columns of calcite and stalagmites, including a column known as “the Dog’s Paw,” which reaches a height of 80 meters (260 feet). The cave is also divided into three main areas: the entrance area, the fossil corridors, and the Bach Nhien passage named after a historical battle. Each of these areas adds a unique flair, reflecting different geological events, making it a natural laboratory for scientific studies.
Biological Diversity Inside the Cave
One of the most exciting features of Hang Son Doong Cave is the primitive forests that exist within it, which have arisen thanks to openings in the cave’s ceiling known as “sky windows.” These windows allow natural light in, creating an ideal environment for plant growth. This biological diversity is vital, housing rare plant and animal species that allow researchers to understand natural formations more deeply. As a result, the cave has become home to many new species that have not been discovered before.
Visiting Hang Son Doong Cave
Organized visits to Hang Son Doong Cave are a unique and special experience, attracting visitors from around the world to explore this magnificent natural landmark. Local companies offer guided tours, allowing visitors to better understand the cave’s history and formations. Attention must be focused on how to protect this cave, as increasing numbers of visitors have come over the years, highlighting the need for sustainable management to protect the environment and safety in this unique area. Touristic visits contribute to the local financing, which helps protect the environment and facilitate scientific research.
Importance
Hang Son Doong Cave for Scientific Research
One of the most important aspects of Hang Son Doong Cave is its role as a diverse research field. With the increasing interest in studying its unique cave formations, scientists have witnessed opportunities to explore the effects of erosion and historical geological processes. A team of researchers in 2019 discovered that Hang Son Doong Cave is connected to another cave called Hang Thung via an underwater tunnel, adding more dimensions to its overall size. These discoveries provide scientists with a unique advantage for analyzing ecosystems and the impacts of climate change on the environment. Here, Hang Son Doong Cave can play a pivotal role in the changes of the earth’s features over the years.
