The local public course in Traverse City, Elmbrook, has two fairway bunkers shaped like lower Michigan and the Upper Peninsula.
I have seen several other similar features, but I try to forget them as fast as I can. I really don't see the sense of designing features that make sense only from 30,000 feet, although I guess Google Earth has given them more play.
P.S. Google Aberdeen Golf Course in Florida, by Desmond Muirhead, and be prepared to laugh. He did a bunch of similar courses in Japan, but I don't know the names of those.
