Here's a survey problem that is pretty much Nuclear Physics. Either that or Rocket Surgery. Werner Von Braun isn't returning his calls, so I can't say.
The GPS receiver is set up on a punchmark on a 2 in. Aluminum Cap affixed to a 5/8 in. x 30 in. rebar with a concrete collar around it. It has the name of a surveyor on it who spells his name the same way I do. After the rod and cap in concrete was set, a tract was conveyed off using a description calling for the rod and cap marker as it then existed. The "Just-a-Fence-Post" fence post was placed a year and a half later, in 2009, when the wire fence seen in the photo was built to keep livestock in.
Overall View of Corner 355
Well, now we find that the Rod and Cap with a concrete collar around it is in a position 0.18 ft. distant from where it was originally placed in December, 2007. The surveyor who spells his name the same way I do mine knows this from having accurately positioned the rod and cap when it was set in 2007 and I know where it is now using similarly accurate techniques. Pt. No. 355 is where the Rod and Cap was originally set and 355A is where it is now, 0.18 ft. away.
Relationship of Original Corner to Rod and Cap as Found
Monuments control, right? Any nuclear physicists want to explain the physics of the situation? The dashed grey line in the photo below is the outline of the concrete collar that has been uncovered and is in contact with the "Just-a-Fence-Post" fence post.

Should we send this extremely complicated problem off to the Max Planck Institute or should we just venture an explanation ourselves?
