Having dug down to bedrock around the tree, we now turn our attention to the other side of this section of the back yard.
It appears that we have one very large rock under this patch of the yard, so first lets try to outline the rock.
And then take the dirt off the rock between these two sides.
Once we remove the dirt, we can see that it is not one big rock but two big rocks, plus something there in the far back. So the next problem is to break it into manageable pieces.
And then haul the pieces out to the front of the house, leaving a big hole where the rock had been.
A little clean up and we are done with this part of the backyard.
