Interesting Fact #1057 - The Earth

The deepest that humans have ever drilled into the Earth is 12,261 metres (40,230 ft) .

(
The drilling took place on the Kola Peninsula in Russia. Some interesting things were discovered within the earth's crust, as the drill made its way approximately halfway through the earth's crust it exposed rocks that were 2.7 billion years old, and along the way they found a fractured area of rock 3 to 6 miles beneath the surface that had been thoroughly saturated with water. Temperatures eventually reached 180 °C (360 °F), making deeper drilling prohibitively expensive.)
