The deepest cave map on Earth dates from the Cretaceous period

The 2,197-meter cave in Georgia has been attracting hundreds of explorers from all over the world to discover every year.

Recently, scientists have created a detailed map for the deepest cave on Earth - Krubera cave . This cave is located in the block of Arabika - one of the highest limestone mountains in Abkhazia, Georgia. It was formed during the Cretaceous and late Jurassic period, the period of dinosaurs still hegemony on Earth.

This area has many deep caves from about 500m to nearly 2,000m. The Arabika's southwest is adjacent to the Black Sea.

Krubera cave also has another name is Voronya cave or Voronja (meaning crows cave in Russian). The origin of the name Voronya comes from the fact that when researchers came here in 1980, the entrance to the cave was sealed by the crow's nest.

The cave is named after the Russian scientist - Alexander Krubera

In the early 1960s, Russian scientist Alexander Krubera and other explorers conducted the first cave exploration in this valley and found the entrance to Krubera cave mouth. Therefore, his name was taken to place this mysterious cave.

Since the 1980s, explorers have conducted many polls in the hope of knowing the true depth of the cave. The current record of 2,197m was set on August 5, 2007 by an international expedition of 56 people, but the journey of discovery has not reached its end.

Krubera cave has been recognized as the first cave in the world with a depth of over 2,000m

Scientists believe that this record may also be changed. But with this achievement, Krubera cave has been recognized as the first cave in the world to surpass 2,000m in depth.

Now scientists are still researching to conquer the challenge of this "bottomless" cave to be able to create more detailed maps about it.
