The four stone walls that define the center square of our garden were our first project here. Both top edges needed to be straight. That left a wandering canyon in the center of each top surface. When we find an interesting stone it is placed in these center voids. We were the first humans to see the sharply defined fossils in the newly split stone. These fossils weather quickly but they will last for our blink of existence here. The long dark line across the brown stone looks like a tree branch. I do not understand how wood could from a fossil here. Can any reader help us with an explanation?
