Well, here's what I see. First, the bottom areas are out of focus, so I concentrated on the cliff.
OK, the top yellow circle is around what I think is your "Indian", but I think he's actually a knight. You'll lnotice the tall helmet with a rounded point to it. This basic style of helmet was used by Romanisk soldiers, including even the Mongols. Drawings of the 2 Kan rulers of the Mongols shows that both of them wore helmets with this basic shape, with cloth or chain mail veils around the sides and back. This guy has an eyeball on his left cheek, of all things. The eyeball is white with a black pupil
The yellow arrow is pointing to at least 2 hearts on the cliff face that I think were made by whoever broke off at least half of the width of that trail. I marked the trail with a green line.
The red square at the top of the photo is around a devil looking head that has SOMETHING in it's mouth. Can't tell exactly what.
The 2 blue circles are around a couple of heads that are truly ancient. The smaller one is a European-type face, but the large one is an Olmec head. This site must have been established by a group PRE-DATING the Aztecs. Here's some more strangness.........these 2 heads each have a white eyeball with a black pupil. I have never seen any Olmec heads with white eyes before. If you look at the photos of those found in Central and South America, they all have round eye shapes left natural stone color. THIS head has symbols all over his forehead, bridge of nose, both cheeks, his chin, and his jowls.
The yellow circle to the left is another old man face. To the right is an odd black shape that looks like a cowboy, wearing a tall crowned hat, riding a horse, with 2 mesa mounts in the rear. Yes, I know it's crazy, but that's what it looks like to me.
Next yellow circle down is around a large area loaded with letters, etc. arranged in sequencies.
The lower left circle is around a large, black "7" and maybe a "1". The center yellow circle is around a bunch of faces that are overlapping each other. The small yellow circle is around a man's face that looks injured.
The red circle is around a face that is either a snake face or a cat's face. It has 2, large white eyes with vertical black pupils.
There are a LOT of other symbols and things that I did not mark. Too much marking will usually cover something, so I don't.
If you're wondering about my comment about some group destroying the trail ledge; I've seen photos of other things someone, thought to be the Spanish, has done. Also, a couple of members have found some sites with white paint put over somethings. One member calls them the White Paint Brigade. They are VANDALS at best. You may or may not be able to clean off enough of the "paint" to see what it was that they wanted to cover.
