Strange sights on Google Maps

Google Maps is the most fun thing in the world. Try these:

Here's a cool shape on the ground. Extraterrestrial? I know, but I won't tell.

This is apparently Area 51 and there appears to be a flying saucer in the middle of the screen. (Or is it just a water tower?)

Some regular crop circles.

A face on the ground in Canada? Pretty cool.

Yep. Maps. Who needs video games?
