A megadungeon orientation point

A multi-level megadungeon, but every level has a spot in it that is the same on each level (perhaps a grassy area, or each one has the same tiles on the floor) and those spots are directly above or below all the others of the same type.  It works as a bit of a lateral orientation point.
