Big kudos goes to RednekF350 for posting the link to iMAP and the 1930's aerial photography. From there I took a snapshot of Mary Ann Forge from 1930, 2000, and a USGS topo from USATopoMaps and put them together in the image below.
It looks pretty clear to me, although I hate to admit it, that there was a bog in that area. Also note the clearing with a lot of roads to it marked "Old Clearing" and how it's now totally gone. Maybe there was a packing house there at one point in time? Maybe there's ruins there now?
Either way, check out how the flow of the Greenwood and Pole Bridge Branches have changed.
