Google Earth
Google Earth allows people to use satellite images to get a birds-eye view of the world. This is free for anyone to use.
This means that a few people with a lot of time on their hands have closely examined thousands of images to find some pretty spine chilling events.

In the countryside of Chile, there’s a famous site dedicated to Coca-Cola made up of 70,000 empty bottles.
Nobody knows where this mysterious monument comes from, but it must have taken dedication to making them spell “Coca-Cola”. It can clearly be seen on Google Earth if you know what you’re looking for.
