The Well To Hell

This exercise was to see who could dig so deep that the heat and pressure would compress the hole and you couldn't get your drill bit out.

I read somewhere that the Earth's mantle runs around 25 miles thick on the average.

Hughes Corporation Engineering and the good American Race to be there first, could have got us there.

When I was still in school (Texas) some drilling company got us out of class for a month.  They made us build, like, 50 of these electronic modules, that they'd put down the holes, to measure, I forget what.


But solder would melt before the boxes got down far enough. So we'd just keep lowering boxes down,  hoping to get enough measurements for a consensus.

The race to dig the deepest hole was much like the Space Race which was happening around the same time. The United States was the first country to start drilling, doing so in 1961 with Project Mohole. A drill ship was stationed off the coast of Guadalupe, Mexico, and it drilled five separate holes. The deepest of these reached 601 feet into the sea floor, which was positioned underneath 11,700 feet of water. Ultimately, however, rising costs forced the project to come to a halt. Congress decided that money should instead by allocated towards sending people into space and to pay for the Vietnam War. That’s when the Soviet Union stepped in.

How Deep is the World’s Deepest Hole?

How Deep is the World's Deepest Hole?

In 1970, Soviet engineers began their deepest hole project. They started their drilling in the Kola Peninsula in Northwest Russia. They dug for about 25 years, until they no longer had the funding or the resources to continue.

How deep did they get? The hole itself is 7.5 miles deep (12 km), but interestingly, it is only 9 inches wide in diameter. The Kola Superdeep Borehole is deeper than the Mariana Trench, the deepest point in the ocean. Jokingly, some of the workers on the Kola Superdeep Borehole claimed they could hear the people screaming from Hell the deeper down they got. That’s why it’s sometimes referred to as the “Hole to Hell.”

Now we have to manufacture enough beer and pop cans to fill it.

I've seen the biggest man-made excavation in the world, the Kennecott copper mine, Utah.  .6 mile deep x 2.5 miles wide.

It's a pretty big hole.

Even bigger when you consider it was once a mountain. Then flat. Now a hole. And going deeper.
