I am not completely sure about meaning of these sings but I have a few ideas and I would like to hear what do you guys think. At first you see a cross that point somewhere and on top of that there is a circle hole ( might be a water hole) and then when you follow that cross there is a big rock with rectangle on it which means a female grave and bottom of rectangle there is X X X signs. About 1m above that X signs there is another cross that points out somewhere else. and when you follow that last cross to right you can see main big rock at the end with a sculpture of a big human head in lying down position. you can clearly see circular 5 holes on ears of sculpture and other rectangle holes. This is what i could say genereally. All other ideas and comments welcome here
