Rocks weather and erode into all sorts of shapes that the imagination can interpret as familiar objects. Like clouds, these rock formations, sometimes called mimetoliths, may look like different things to different people. But some are unarguably humanoid.

We've collected some great examples of rocks that look like human faces or heads from all around the world for this gallery. Some look like queens or presidents, and some are quite famous, like New Hampshire's Old Man of the Mountain. But we know there are a lot more out there, so if you know of good examples (or even better, have a good photo of one), let us know.

The Grey Man of Merrick sits at the base of Merrick mountain in Scotland's Galloway Forest Park. The man is a mimetolith within a mimetolith, as Merrick is the index finger in the Range of the Awful Hand.
