Check your picture with no.3. If possible use a magnifying glas and you will notice what I have said.
Angel_09,
Try using dowsing on No.3 rock and if you have the gift of dowsing, it will give you an answer. Dowsing has unlimited capabilities, not limited to a distance of a few meters, one will be a continent away and would still come up with plausible answers. Ever heard of map dowsing, it does work and also it has limitless potential, can look for water, metals, gems, people, what ails a person and much more, one can even ask if a persons character, like, can he be trusted. The rocks or boulders posted are not markers, they are just natural rocks. If you see footprints, left or right, there will be no mistake as the prints is very clearly defined. Most markers that I have seen is clearly defined, be it be a footprint, a palm of the hand, an eye or an X or a hole, that is why I salute the Japanese as they are really experts on stone craft. One can almost say they etched those markers with laser but laser was just fiction at that time.
My 2 cents worth.
