Is there any relationship between the large stone and the monument?
The stone was and is the original and exact corner. When Wharton was surveyed they came up with the idea to place the monuments away from the stone rather than next to it. Depending on the terrain the monument is usually 4 to 12 feet away and that number is stamped into the monument with a line pointing towards the stone. When there is a stone present the monument is NOT the true corner, the stone is. If a stone is not present and never was, the monument is the true corner.
A year or so ago I walked the full property of the Stamping Mill on Carranza Road and discovered a minimum of 4 mistakes in the recent survey of that tract. At a couple corners where a stone was present and easily visible, the surveyor used the monument as the true corner. The monument was 10 feet away from the stone and it was 300 feet to the next corner. This meant there was an error 10 feet wide that narrowed down to the next corner 300 feet away. That is a large chunk of property. The state owned the property next to it so it really did not matter. However, at one corner it was private property so the surveyor in effect took a 10 foot strip of land 90 long away from the state and in effect gave it to the private property owner.
I contacted RednekF350, a licensed surveyor, and with Jessica we visited these locations and we reviewed my finding and I was correct. This shows a stone that was present but the surveyor used the monument hidden behind Rednek.
