me too, but is that rock or petrified rock?
Almost looks like cement ... or tufa. Really NICE!!!
It's not petrified wood. Not exactly sure what it is. I know it's a schist that has some crystalline structure and there are layers that erode more than others. There are outcroppings of it in the woods and pieces have broken off over time. I also find it on stone walls.
