Pond Boss Forums POND CONSTRUCTION Selecting a site Pond in old caliche pit?

I don't have to rip it if it has any moisture in it. When it dries real good it's a different story. The hardest dirt to push is the dirt right above it. That layer is black with a little yellow showing. It has no gravel in it at all and doesn't want to break. It stops the old D6 in its tracks--or is that "on" its tracks?
