Thanks Jim. Looking at the slope behind the pond, my pictures never capture what I see. There are rocky shale cliffs, overgrown with mosses and the trees are kinda crooked. One could imagine someone trying to create a Bonsai scene, this place could serve as a model. We refer to it as the "Japanese section"!
and I would not be too surprised if some of these caves serve as den for the numerous Black Bears living in our area.
