Last weeks map was a plat by the GLO in the patent. This weeks map ties in to that survey and extends it several townships to the South and it is in NAD27 State Plane, very high tech for the time. It also has a T.I.I.T.F. Resolution and field notes. The map is a Reconnaissance Survey. I’m not sure what that is, but if you follow the notes they set section corners like a survey or a dependant resurvey or a resurvey or even a boundary type survey. Read the field notes they are very interesting. If you’ve worked in or visited the park you will understand what they are talking about. I wonder if this is one of the first “Surveyor’s Reports”. Also there is a possible mistake with one of the corners, can you find it?

I don’t believe that the map is readily posted to any website. If you know of it please share it.
