Well it's simple. At the protected campsite you'll find a large bed shaped outcrop, numerous funny shaped stones that resemble various things not always the same like mushrooms or bears. You'll see piles of marker rocks. Basically they practiced lower levels of freemasonry stone masonry. Certain markers are more important than others.
You should see abstracts of hands or fingers possibly foot monuments with at least a few toes. Some might be huge others may be small. Lichen will be there as green was an important color for looking in the green for the next sign or symbol. "A" maps can be made from a crack in the rocks or from veins of quartz which is more important. Quartz and light sky signs are royal but so are some shadow signs it depends on the context of the symbol string just as in other language.
Thanks Bill. When you said rock monument garden, I thought that some of the monuments might have been created for sentimental or entertainment purposes and not related to treasure.
