17-Apr-2011 -- This was a very interesting visit. From satellite photos beforehand, I knew that the confluence point lay in a wooded area near a subdivision (and that I should approach the point via the nearby power line trail, to avoid bothering residents).
I was surprised to find, however, was that the woods surrounding the confluence point have recently been cleared. Apparently the confluence point will soon be claimed by 'urban sprawl', and will become part of someone's home or back yard.
It will be interesting to see what becomes of this point.
