The routing of the Aucilla River is in question in this area.  I can't see it at all in the satellite photos, and the tree cover is sparse enough I believe I *should* be able to see it.  It's possible that, rather than flowing as shown, it goes up to alongside the CSX railroad and follows it until it merges with the Masse Branch, and then they flow to the Massey Ferguson Pond as one.  But someone with better knowledge needs to confirm.
