The Yew primitive I'm working on has a strange feature where the heartwood seems to swell up through the sapwood in a ridge. Pictures in books tend to show perfectly symmetrical logs with the heart sap boundary concentric with the growth rings... but real life isn't like that. I've met it before on an English Longbow, I just ignored it on that one, see this post:-
