The bottom part of the hill, below the retaining walls:
This area is getting more dirt and we are talking about removing a few more trees.
Just a bunch of photos to show different views:
I wish we could have made the lower wall area larger - it would have made a nice arena...
Grate over drain in the lower wall. This was already in the hill when we purchased the house - the original home owner's attempt to control the erosion. We just extended the pipe up and added this nice grate.
That piece of metal sitting on the wall goes over the grate. The pointy things sticking up from the metal go into the ground so no hooves get poked.
Another view of the upper wall (and the top of Sam's tail...):
These photos really don't do the new areas justice. The slope looks pretty bad here, but I think it is the angle of the camera. This area is quite flat.
