This looks like a small town, but in fact it's a diamond mine!
On the tundra 36,000 feet below are the barely accessible Snap Lake Diamond Mine and Airport, built by De Beers on the shores of remote Snap Lake, in Canada's Northwest Territories.
Processing takes place in the red buildings in front, and you can see the runway of Snap Lake Airport at the left rear of the developed area. The diamond mine itself is entirely underground.
