You are NOT going to tell us that you have searched the hills to see if certain monuments have been accepted and in this search, you find nobody even knows about the "spurrious corner"; therefor you are going to destroy them? Tell me, you don't mean that?
Yeah! I am telling you that you had better search the hills, the records and the Death Certificate Index if necessary. The caveat being you absolutely must be right when you do this. I used to argue with the late, great Richard Schaut over Bryant v Blevins. He is gone, but the argument endures. Your survey should reflect the intent of the parties. If it doesn't you need to fix it when afforded the opportunity.
I know you are sincere , Keith. But I also know your beloved Bureau has set their boundary monuments right next to our NPS "boundary monuments" on more than one occasion. There is theory, there is policy, and then there is reality.
