Biblical Flood
But while some enthusiastic commenters have jumped on this discovery of subterranean water as proof of biblical floods, this phenomenon is instead assumed to be the result of heavy pressure pulling oxygen and hydrogen atoms out of the rock. Impermeable rocks subsequently caused the newly created water to become trapped below the surface.
An Environmental Hazard
The timing of the closure of the Kola Superdeep Borehole coincided with the collapse of the Soviet Union, and the project was permanently shut down by 1995. Today, the site is flagged as an environmental hazard, although some remnants from the experiment can still be seen by tourists in the nearby town of Zapolyarny, some six miles away. And, impressively, researchers have yet to beat their record, which means that the borehole remains the deepest man-made point on the earth.
