The Deepest Hole on Earth
“Because it’s there,” the British explorer George Mallory once responded, when asked why he wanted to climb Mt. Everest. (It’s not clear if he ever got there.) During the Cold War, both the United States and the Soviet Union looked the opposite direction and launched rival projects to drill as deep as possible into the Earth’s crust. The United States made it about 600 meters; the Soviet Union, about 12,000—resulting in the Kola Superdeep Borehole. The project only shut down in 1992 after the Soviet Union itself went into a hole. Learn more about this project and others like it, then discuss with your team: what, if anything, should be the next frontier humanity tries to reach—and why? And are races—and heated rivalries—the best way to get somewhere quickly?
Twelve kilometers down, the Kola borehole struck rock so hot — about 180 degrees — that it flowed like putty and seized the drill, forcing the dig to stop. Along the way it turned up something stranger: water locked inside solid stone, and microscopic fossils two billion years old, far deeper than anyone believed life's traces could survive.
Key concepts
- The Frontier
- The edge of where humans can reach — up into space, out across oceans, or down into the Earth; defined as much by difficulty as direction, wherever 'we've never been' meets 'we badly want to go.'
- 'because It's There'
- Mallory's answer for why climb Everest — the pure exploratory impulse, reaching a place simply because it's unreached, contrasting with strategic motives like prestige or resources.
- Rivalry As Accelerant
- Competition between powers can hugely speed hard achievements — the Cold War drove both the Moon landing and the Kola drilling, concentrating money, talent, and urgency.
- Knowledge Versus Extraction
- Why reach a frontier — to learn (Kola studied the crust) or to take (minerals, advantage)? The motive shapes what we do once we arrive.
What to know

01
Rivalry made the impossible fast — Cold War competition pushed the Soviets 12 kilometers down and the Americans to the Moon on timelines no peacetime budget would allow.
