Neal, I can't picture any other chimney system to the east of Feather Canyon's start. Rituals and Magic starts 200 feet to its northwest (that's to the right if facing the start of the routes there) and being to the northwest (not east) from Feather Canyon's start would be consistent with your comment that after the wrong route "we went down and back southeast until it became obvious to us where the route was."
Sorry, but without being there I don' think I can offer any more.
