Good day. Guys please give me an answer to this signs it tells me something. There are a lot of them in almost every rocks the whole 24 hectares of our farm land.
This one looks like it tells me something of an object underneath
This one really looks like a head of a turtle (i don't know..)
if the cover your acreage and they are the same sort of stone with the same fissures and lines, then you need to consider that they are natural, especially if there is nothing that slaps you in the face as undeniable.
Do the "arrows" line up across your property and the last one points down at the turtle head? If so, they may be markers. And I would be checking out/dig at the creek. Otherwise, I go along with unclemac.
you look for landbased tree markers. those that are century old mango trees, balite tree or fire tree. it implies there is a chamber or dozens of chamber in your land. look also for buri trees or any century old fruit tree. but the only trees that signifies an entrance to a chamber are mango trees, balite or acacia tree, or fire tree.
as for the stone, you really cant tell the difference if it is natural or not. they all look the same.
