Canada's underground giant hole is creepy. The reason for the formation of the underground giant hole is a mystery
4hw.org: there are so many mysterious gifts from nature in the world. Some of them are really daunting, but mystery drives this curiosity to find out. A member of the Canadian cave association has found an underground cave. He doesn't know what kind of shape this mysterious cave is.
Two members of the Quebec cave society, Luc LeBron and Daniel Cullen, found a huge cave underground in Montreal, Quebec, Canada. The newly discovered cave is at least 200 meters long and about 6 meters high inside. Two cave explorers have believed for years that there should be a series of caves connected to the discovered San Leonard caves.
In 2014, they found a small crack. After nearly three years of exploration, they finally entered the cave in October this year. According to the investigation, the cave was formed 15000 years ago. There is an underground lake inside, and the cave space is huge. Due to the deep underground aquifer, part of the water in the tunnel is very deep, so we can only use inflatable boats to move forward.
According to reports, two explorers were unable to move forward due to the high groundwater level when they reached about 150 meters from the cave entrance. They plan to enter again when the water level drops in February next year, and they are expected to push further 50 meters into the cave in February next year.
The genesis of the newly discovered cave is believed to be the same as that of its' neighbor 'San Leonardo cave, which was formed in an ice age on the earth, about 15000 years ago. The huge pressure of the surface glaciers leads to the cracking of the underground limestone layer, which creates this unique landform.
