Feb 19, 2015 · The Kola Superdeep Borehole was just 9 inches in diameter, but at 40,230 feet (12,262 meters) reigns as the deepest hole. It took almost 20 years to reach that 7.5-mile depth—only half the ...
Nov 10, 2009 · Discover Kola Superdeep Borehole in Murmansk, Russia: The deepest hole drilled in the name of science, where evidence of Precambrian life was found.
At ten kilometers, they hit rocks that were 2.5 billion years old, saturated with microscopic plankton fossils. Temperatures rose to 180 degrees Celsius and quickly climbed. Stones turned ductile and viscous. Drills lost footing in a molasses-like substance. When technology allowed them to go no further, the scientists started to listen.
