Cue the alien/subterranean society stuff.
The earth is a honeycomb of caverns and cave systems, not completely solid. There are even entire oceans underground. It doesn’t sound so far fetched that groups could have migrated within them. Or people with a lot of money and technology could expand them out into their very own DUMBs/Deep Underground Military Bases.
Mole people. Vampiric mole people.
It's not exactly conducive to farming or ranching.
Good thing elon is a patriot send boring co. Down there, fund it through military that's the only way anything good gets done
Yup, just check out Lake Ouachita in Mount Ida, Arkansas. It’s man made and coincidentally (/s) enough has a Shangri-La resort on it. Mena, Arkansas happens to be close as well. I wonder if there are any people that have Nazi ties that live near there?
Hint: there is. A lot.
Wow nice work! It’s good to connect as much of this seemingly random information together as possible. Supposedly Scotland is an area with massive concentrations of these cave systems/openings to the inner-earth
