These photos sure show a LOT of overburden at the base of those cliffs that are just too much to have come from those tiny cliffs.
That large standing pointer stone in the first photo is man-placed. That material is unique to some place else. When the sun is shining from the opposite direction, it should make that vertical piece really show up; as well as that arrowhear pointer that is lying flat, pointing to the vertical one.
That large figure in the 3rd photo looks like either a "g o" or a "j" overlaid on a "O". The "j" might actually be a fishhook symbol that "pulls" you in the direction to go.
A "g" and "O" would give the value of 26 and a "j" and "O" would be 29. If the figure is a "j" overlaid onto an "O" and is also a fishhook sign, it would be "pulling" the observer in the indicated direction for a distance measurement of 29 units.
In the second photo, at about the 11 o'clock position from the upright pointer, is a black church cross on the top of the cliff, at the lip.
EDIT: In the 4th photo, that hook is pulling you to that large area with the big rock pieces. That looks like a large "fill" area as when someone covers up an operation of some kind.
