A mimetolith is a natural rock feature that resembles a living form in nature — usually a face a human head, or animal.
Erosion and weather can combine to make rock formations look like all kinds of things, from human faces to animals. They're called mimetoliths and we've taken a look at four of the most famous.

This all being said these natural shaped rocks have been used by all cultures to describe a place.
Pareidolia is usually when we see faces if I remember correctly.
Yes, & they took full advantage of anything Naturally Occurring, & were masters at making things they did look questionably
& very much persuadingly natural.
Pareidolia,
Would that be faces supposedly that are not actually shaped or carved, but seem to be present
in the various shades & colors or variations of out cropping or terrain along a hill, mountain, valley, maybe trees or landscapes with shadows, silouettes, light, etc.
But when man has obviously touched, manipulated by the carving, moving, & or particularly the methodical setting of rocks & boulders, for the purpose of marking perhaps a trail or treasure area, or a burial vault or crypt. Then that would be a real marker or monument, because there is definite evidence of man's manipulation. Even to the extent of alignments with solar & lunar events. Such as the winter & summer solstice, etc.
The ancients were well informed & had great knowledge of such things, & went to great lengths to bury, build & align. Just look at various places in N. America, such as Mesa Verde, Chaco Canyon, on & on.
And sandy1 & Quinoa have shown various pics of huge markers you won't see in any book or view on any documentary, of the fantastic work of ancients, even here in US.
So many of them boulders or cliff faces so massive in size & weight, that in our modern technologically advanced age with all that is known, no one really knows to this day, exactly how they did it.
This is what the OP of this thread is asking about. A couple of the pics he shared, are appearing to be part of a massive vault or crypt burial entrance, that is set up with multiple ton boulders, carved with shapes, holes, depicting forms of things known to have been used from the ancients, all the way through to the Conquistadores & Jesuits, who were well informed & studied in all such things. This evidenced by the types of markers they made, added to & left for the purpose of being able to recover treasures whenever, later on in the future. Believing that their methods would not be understood or deciphered, because their secrets would remain unknown of the masses.
They were right to the extent that some of their caches are still so much unknown, that many may remain, & are only in the last half of the last century beginning to be even understood, much less ever recovered. Many are trapped so bad, with unbelievably heavy boulders.
Though some are death trapped to the point it's impossible to work safely or even at all, on discovering or uncovering anything they may have left there, without some of the biggest of big heavy equipment.
This is one aspect of why archaeologists will deny any such things of antiquity exist, & may not even fully understand, or want to acknowledge, or maybe believe the existence of such things. Even though some have sought to gain knowledge from them, ernestly.
Either they don't know,
or they are simply just not going to be talking about it any time soon, or most likearnestly. Except when they do something they can release an article about.
