Cool Optical Illusion Collection #4

Crater Mound of Dirt?

Just a mound of dirt right. Wait! Before you go to the next optical illusion, take some time to examine this picture. It isn't a mound like you may think but a giant crater. I think this picture actually comes from the moon. In reality, this is not a giant mound of dirt, but a crater. The dark area in front is actually the shadow in the depression where it was hit by a meteor.

Although it may look small, it actually may be several miles wide, which is almost another optical illusion - that's two for one!
