The spot was on private property, and no laws on picking up “rocks” off the ground that I know of. Definitely not wise to mess with sites like that , the spirits will start talking to you, lol. I’ve been looking into this for long while now, so while most might not agree, and I probably am not 100 percent correct in my thinking, the truth probably lies in the middle ground. No one knows how old the “rock pile” sites are, not really cairns or trail markers, how do you date a pile of rocks.
