The USSR’s Kola Superdeep Borehole project, initiated in the 1970s, reached a depth of 12.2 kilometers—about one-third of Earth’s crust—over 20 years. This ambitious endeavor uncovered ancient fossils and unexpected water deposits but ultimately faced limitations due to extreme heat and pressure, causing the borehole to collapse before reaching deeper layers.
