Forget about that, I just learned there’s a salt mine under Detroit!

There's also one under Yerevan, Arnenia. Funnily, the altitude differences in the city are so large that the bottom of the mine is still higher above sea level than the city center.

I'm excited for them too!

Haha I definitely googled that, and I was not disappointed

Was missing the Iranian nuclear sites and other underground bases in this.
Also, I knew Baikal lake was deep, but not how deep its sediment layer is! That looks like something out of a Lovecraft story...

Lake Baikal sediment layer almost as deep as the Mariana Trench:
[...] and below this lies some 7 km (4.3 mi) of sediment, placing the rift floor some 8–11 km (5.0–6.8 mi) below the surface, the deepest continental rift on Earth.
> However, in May 2008, a new record for borehole length was established by the extended-reach drilling (ERD) well BD-04A, in the Al Shaheen oil field. It was drilled to 12,289 m (40,318 ft), with a record horizontal reach of 10,902 m (35,768 ft) in only 36 days.

I forget how cool Lake Baikal is until it shows up randomly and I'm reminded to go look it up again.

What are all those oops for?
Cycl0ps 23 hours ago [-]
collapses and floods it looks like. Here's the oops for the Pantai Remis mine
Lake Peigneur was swallowed by a whirlpool like in an anime, in a sad drilling that took away entire boats. The salt geologic bubble under the lake can absorb gigantic volumes of water, and a drilling for the exploitation of petrol initiated the hole.
I played that game way back when - I highly recommend it.
Edit: thanks, that's an(other) hour of my life I'll never get back :-)

Nothing of great interest. That's a tiny scratch in the surface of the planet, less than 1% of the radius.
On the other hand although we lack the technology you'd need to destroy the damp rock where we live, we only live on some dry-ish outside surface parts of the rock, and we could trash that part and drive ourselves extinct. "Oops"

They were asking why the two deepest holes, despite being nowhere near each other, dug decades apart, are 99.3% of 12km and 99.5% of 12km respectively. Was BP symbolically honoring the russian scientists? Does the earth have an extremely uniform material property that happens to be at a very round number of km? Just a complete coincidence all around?
(I asked AI, and it says coincidence, since BP stopped drilling once they hit oil, and the russians stopped drilling once they hit some melty rock.)

Also in both cases economic reasons. BP drilled to reach oil which makes economic sense, but AIUI the Russians wanted to keep drilling but eventually central government wouldn't give them any more money.
But yes, largely a coincidence. I think humans would see the same "pattern" if it were slightly more than 12km. We like patterns, we're the superstitious pigeon experiment but at a ludicrous scale. I would like to think the patterns I've seen point at some underlying more important truth - but the pigeon thought so too.
Anyone who wants the large image can click/tap the image, but the revere is harder to do.
In the other direction, Mt. Everest is 8,848.86 meters above sea level. I guess we don't include Lake Tahoe and/or Crater Lake because even though they're deep(ish), their bottoms are above way sea level?
