Not posted here but elsewhere, it has been explained as a 'mine' entrance with the miners road leading to it.
If you look it up on Google Earth (it's called Indian Head) there is a photo taken by a paraglider that shows you it is a valley, so it is a negative almost where the head is indented rather than carved into a hill. Interesting....reminds me of the Colossal Head on Mars which also seems to be an indented structure rather than a hill.....
