The Great Blue Hole in Belize is very mysterious and dark. It is one of the largest underwater caves in the world. Even in the recent hundreds of thousands of years of geological changes, there have been a large number of natural wonders that have so far been unattainable by human technology.

Whether it's Mount Everest, the world's highest peak, or the Grand Canyon in the United States.

The same is true of the largest underwater cave in the world that I will introduce to you today. It has a very magnificent natural scene and attracts a large number of diving enthusiasts to challenge it every year.

This is the Great Blue Hole of Belize located in the Caribbean Sea. The so-called Blue Hole is an underwater cave with a very special structure. After achieving a perfect coexistence with the surrounding reefs, a natural scene like an azure ring is formed.

This phenomenon is very common in Earth's vast oceans. The reason why this Great Belize Blue Hole is special is that it has a diameter of more than 300 meters and a depth of more than 100 meters, which makes it a number of the world's highest. It is also rated as one of the top ten geological wonders in the world.

In the study of geography, the Great Belize Blue Hole has always been a difficult problem to overcome. In 2018, using the most advanced storage technology and diving equipment, scientists have successfully drawn a specific 3D map here.

However, there is still no reasonable explanation for the formation of this big blue hole and some specific details. The only conclusion that can be drawn now is through the study of the underwater topography in the cave and the analysis of some minute milestone samples. At a certain moment in the past, there was a natural factor that caused great changes in all aspects of the conditions here, thus forming the spectacular sight that tourists see today.

Many explorers and scientists later determined the formation time of this place to be 15,000 years ago. It is believed that with the further development of science and technology, the research on blue holes is also expected to achieve greater breakthroughs.

On the other hand, the Great Belize Blue Hole is the most difficult and most popular diving destination in the world. The challenge here is not only due to its huge area and unparalleled depth.
