Fun Facts About the Great Blue Hole – About the Great Blue Hole

The Great Blue Hole is a large underwater sinkhole located off the coast of Belize in Central America.

It is circular in shape and measures around 300 meters (984 feet) across and 124 meters (407 feet) deep.

The Great Blue Hole is a popular spot for scuba diving and attracts divers from all over the world. The unique geological formation of the Great Blue Hole has made it a popular site for scientific research, as well as a stunning destination for tourists.

Fun Facts About the Great Blue Hole – Basic Facts & History

The Great Blue Hole was formed during the last ice age, around 15,000 years ago. During this time, the sea level was much lower than it is today, and the area where the Great Blue Hole is now located was actually a limestone cave system that was above sea level. As the ice age came to an end and the sea level began to rise, the caves flooded and the roofs collapsed, forming the distinctive circular sinkhole that we see today.

The Great Blue Hole was first explored by Jacques Cousteau and his team in 1971. Cousteau’s research helped to popularize scuba diving and led to increased interest in exploring the world’s oceans. Since then, the Great Blue Hole has become one of the world’s most popular diving destinations, attracting thousands of visitors every year. In addition to its popularity among divers, the Great Blue Hole has also been the subject of scientific research, with scientists studying the geological and biological characteristics of the area.
