Belize's Blue Hole Mystery

The Great Blue Hole in Belize is a giant marine sinkhole off the coast of Belize, near the centre of Lighthouse Reef. It is a world-class destination for scuba divers, who are attracted by the opportunity to dive in crystal-clear waters and see a myriad of species of marine life, including tropical fish, sharks and coral formations. The hole is circular in shape, over 300 metres across and 124-125 metres deep. It is the largest natural formation of its kind and is part of the Belize Barrier Reef Reserve System, a UNESCO World Heritage Site.

The Great Blue Hole was formed during several phases of the Quaternary glaciation when sea levels were much lower. Analysis of stalactites found in the hole shows that formation took place 153,000, 66,000, 60,000 and 15,000 years ago. As the ocean began to rise again, the cave was flooded.

The Great Blue Hole was formed during the last Ice Age

The Great Blue Hole in Belize is a giant marine sinkhole located off the coast of Belize, near the centre of Lighthouse Reef, a small atoll 70km from the mainland and Belize City. It is a world-class destination for recreational scuba divers, who are drawn to its crystal-clear waters and myriad species of marine life, including tropical fish and coral formations.

The Great Blue Hole is circular in shape, over 300 metres across and 125 metres deep. It is the world's largest natural formation of its kind and is part of the Belize Barrier Reef Reserve System, a UNESCO World Heritage Site.

The Great Blue Hole is characterised by its vast expanse of interconnected underwater caverns adorned with stalactites, stalagmites, dripstone sheets, and columns. These awe-inspiring structures are believed to have been formed within the caverns long before the area became submerged. The process of sea level rise and cave flooding occurred in stages, as evidenced by the ledges found at various depths within the Blue Hole.

The unique geological formations and marine life of the Great Blue Hole continue to captivate scuba divers and nature enthusiasts from around the world.

It's the largest sea hole in the world

The Great Blue Hole is the largest sea hole in the world. It is a giant marine sinkhole off the coast of Belize, near the centre of Lighthouse Reef, a small atoll 70km (43 miles) from the mainland. The hole is circular, over 300 metres across and 124-125 metres deep. It has a surface area of 70,650 square metres.

The Great Blue Hole is part of the Belize Barrier Reef Reserve System, a UNESCO World Heritage Site. It was made famous by Jacques Cousteau, who declared it one of the top five scuba diving sites in the world.

The Great Blue Hole was formed during several phases of the Quaternary glaciation when sea levels were much lower. Analysis of stalactites found in the hole shows that formation took place 153,000, 66,000, 60,000, and 15,000 years ago. As the ocean began to rise again, the cave was flooded.

The Great Blue Hole is a popular destination for recreational scuba divers, who are attracted by the opportunity to dive in crystal-clear waters and see a myriad of species of marine life, including tropical fish and spectacular coral formations. The marine life in these areas includes nurse sharks, giant groupers, and several types of reef sharks such as the Caribbean reef shark and the Blacktip shark.

The Great Blue Hole is a vast expanse of interconnected underwater caverns adorned with remarkable formations such as stalactites, stalagmites, dripstone sheets, and columns. Scientists believe that these structures were formed in a dry cavern above sea level during glacial periods.

It's a popular diving site

The Great Blue Hole is a popular diving site, attracting divers from around the world. It is a unique natural wonder, formed over 15,000 to 153,000 years ago, and is the world's largest natural formation of its kind. It is a giant marine sinkhole, almost perfectly circular, with a diameter of over 300 metres and a depth of about 125 metres.

The Blue Hole offers divers the opportunity to explore a vast expanse of interconnected underwater caverns, adorned with stalactites, stalagmites, dripstone sheets, and columns. These awe-inspiring structures are believed to have formed in a dry cavern above sea level during the last ice age, before the cave was flooded by rising ocean levels.

The Blue Hole is also known for its marine life, including tropical fish, coral formations, and a variety of shark species such as nurse sharks, reef sharks, and blacktip sharks. The visibility underwater allows divers to easily observe the cave formations and marine wildlife.

Diving in the Blue Hole is considered an advanced dive due to its depth. It typically involves a quick descent to a depth of around 135 feet, a brief stay at that depth, and a cautious ascent. Despite its technical nature, thousands of divers with varying levels of experience have successfully completed this dive.

The site was popularised by Jacques Cousteau, who visited in the 1970s and declared it one of the top scuba diving sites in the world. Cousteau's exploration brought the Blue Hole to the attention of audiences worldwide, and it has since become a bucket-list destination for many divers.
