Stunning carved Martian Stone Head stands at the entrance to a Cave

A recent image photographed by the Curiosity Mars Rover shows what looks very much like an ancient carved Martian stone head that appears to depict a face and it stands at the entrance to a cave.

Considering the shadow under the head, it looks like it is lifted and held by a rock that resembles a hand/arm, but that's just how I see it.


Suppose the carved stone head with its characteristic face is real and for example it is a tribute to an ancient civilization once inhabited planet Mars, then NASA really should take a look inside the cave. Ron.
