There are holes in Mars
This fantastic photo is of Mars. On the left hand side you can see 3 dark holes at the top of the ridge. They register no light, so they must be a hole.
So whats creating holes on Mars? No one really knows, but if they are anything like Earth (which we think they are), then these could well be collapsed volcanic tunnels.
One things for sure, they aint half deep!
