The Great Blue Hole is a limestone cave, the fourth deepest underwater cave in the world. The Blue Hole is located on the edge of the seabed plateau in the Grand Bahama Shoal, about 60 miles (96.5 kilometers) off the coast of Belize. . It is also known as Belize Blue Hole. The shape of the Belize Blue Hole is an almost perfect circle, with a diameter of more than 305 meters and a depth of 123 meters. Blue Hole Cave is also known as one of the top ten geological miracles in the world for its uniqueness.
The depth of 137 meters near the Blue Hole and the stalactites in the cave are obviously not suitable for general divers to visit. There are a wide variety of sharks here. Even though they are famous, they are in a mysterious cave below the sea. Shameless sharks are on the sidelines, I am afraid no one can feel safe. But because of this, it is like a magical magnetic field, which strongly attracts brave diving lover around the world to come and experience it, making it one of the world’s most famous diving sites. This life is not hidden in this blue hole, which means that the master is also awe-inspiring.
The blue hole is one of the caves, Porous, loose limestone domes that collapsed into a nearly perfect circular opening due to gravity and earthquakes, becoming open shafts When the ice melts and the sea level rises, the seawater pours into the shaft, forming a strange blue hole in the lake.
There are reports of the decline of the Great Blue Hole of Belize and the decline of the Mayan civilization. some people believe that the adverse climate conditions such as drought caused the Mayan civilization to decline, and people also found the same phenomenon in the inspection of the Big Blue Cave in Belize. The researchers extracted some silt samples from the deep blue hole at the bottom of a 400-foot reef in Belize’s “Big Blue Hole” and compared it to silt samples from limestone pits in the inland area of Belize. It was found that the two sample eras were between 1000 and 800 years ago, when the Mayan civilization was in decline.
The proportion of aluminum and titanium in the sample was related to the heavy rain The researchers found that the low content of titanium in the sample indicates that the number of tropical cyclones in this period was less than before and the drought was more persistent than before. However, this is just the same between the two, and it does not explain a particular relationship. There are many blue holes similar to the structure of the Great Blue Hole in Belize.
These strange sights are not only the most beautiful places on earth, but also the favorite places for many explorers. The Blue Hole is just one of the mysterious regions of the Earth. This will inspire more people to participate in the adventure In the Ice Age, this cave was once the entrance to a dry cave system. As the glaciers melted, the sea level rises, and the caverns become submerged in the current blue hole. Today, Belize Big Blue Cave has become a famous diving spot in the world, and it has been named one of the top ten diving treasures in the world.
