Finally had a chance to hear Jeff Lucas
One of the first tasks for any survey is to look at federal interest tied to the survey. It can be surprising how much is. At that point it can be argued that it's not so important what the manual says, but what the feds do with it. I never say,,,,,well the feds will never survey here.
Looking at a survey for an old client and need to sectionally breakdown lands in Sections 13, 14, 23, 24 near town and sure enough it's all federal with clear conflicts between math and established interior lines. Game on!!
I doubt Jeff Lucas has gotten involved with this type of survey.
I was told by one guy that the reason he farted pincushions all over 30 to 40 year old recorded, private monuments was due to federal interest lands. That's just another reason to use 'math precision' instead of legal principal. I would argue that the PLSS was enacted soley to lay out private interests, not to wipe out private interests with the excuse of federal superiority
What gets me, is when the BLM can't agree with itself and has set multiple 16th corners, 5 to 10 feet apart (then not bother to record anything about how they reached their conclusion, then they get mad with us for recording the stupidity). Each different corner ends up conflicting with settled lines of occupation, that include a national park boundary and associated fencing.
