I wasn't educated in it. But I did notice the out of place things around. That's what got me interested in sign and symbols. I remember where most of the bent trees are from childhood and some of the carvings. There's several odd head stones that I found when I was a kid. Found a drill hole that goes all the way through a boulder. Haven't had time to go back to that one yet. That one is on my family's property. There is a story about a silver mine in the holler that that boulder is on the edge of.
