Stick the level on top and hammer in a little wedge of rock underneath to bring it to level. Put the wedge of rock in the spot that rocks - like putting a napkin under a wobbly table in a restaurant. If you don't have any wedges - you gotta make them - which should be doable with a rock/ brick laying hammer and the Rose Sandstone. Or you and Cathal can go on a wedge hunting trip at the local stream. cut into the slope where wall is parallel and stair case the wall down the slope. Backfill space between wall and slope. Generally looks weird when attempt to follow slope with wall. - although it can be done.
