Kola Superdeep Borehole: What They Found In The Deepest Hole On Earth

The Kola Superdeep Borehole is the deepest hole on Earth, reaching further into the crust than even the Mariana Trench. #kolasuperdeepborehole #expedition #sovietunion ⚠️ https://www.youtube.com/watch?v=qC9wn-d1WNo&list=PL0H5lrcTOMY8vioCclT9lxRyDsxDxE7rQ 🔦 Everyone knows the deepest point in the ocean, but almost nobody knows about the hole on land that goes even deeper... Straight down through solid rock, in the Arctic, drilled over twenty years by scientists chasing the edge of the Earth's mantle. In 1970, the Soviet Union began this ambitious scientific drilling project to see exactly what lies beneath our feet. They never reached it. But what came up out of that hole rewrote what we thought we knew about the ground beneath us. And no, it wasn't the "screams from hell" that stopped them. It remains one of the most significant attempts to study the geology of the crust directly, pushing the limits of what was technologically achievable at the time. This is the story of the Kola Superdeep Borehole: the deepest hole ever drilled, what the drilling actually found down there, and the real reason it was abandoned. 🧭 Chapters 0:00 The deepest hole on Earth 0:38 The race nobody watched 1:45 The hole itself 4:10 What they thought was down there 5:20 The 3 things they actually found 8:21 What stopped them 9:24 The screams from hell 10:23 What's still down there 🌊 SUBSCRIBE for other ocean explorations! https://www.youtube.com/@UnchartedDepthsOfficial?sub_confirmation=1 Thanks so much for watching!
