Mars is a pretty wild and wonderful place, and an image posted to the NASA science blog and Astronomy Photo of the Day this week is a brilliant example. It shows what appears to be a mountain... but completely hollowed out.
While it's not actually the product of some strange mining experiment, the formation is indeed hollow. What you're looking at is a lava tube 'skylight', the product of ancient volcanic activity below the surface of Mars.

I have always thought the Martians probably lived deep under the surface.

They are on the moon too.
We might use them to build bases. People will be shielded from radiation, temperature extremes, and micro-meteors.
