I thought I would give this a go, it is a wall I build last spring and I am fixing to add another one here in a week or two. I live on the side of a mountain in Tennessee. Unless one of your legs is longer than the other one, you learn how to terrace your yard in order to have some level ground. I added a few more photos in my post to this one, one is of a wall I put in for my waterfalls on my koi pond. I think it more fun going into the woods to find the rocks, but being able to see them every day is pretty rewarding.
