<<( since where would all the soil go after terracing?) Anyhow just a thought!>> There isn't any soil to spare - you just build your terrace wall and fill in from behind. This means the back of the terrace is is nearly down to rock (around here, anyway) and behind the wall is the deepest, best earth. in fact you rarely have enough!!
