Meigs Line, the 1802 survey line from Fort Southwest Point (Kingston) to Mt Collins (Meigs Post). The older Hawkins Line is eastern portion based on some of the survey marks. The actual surveyed Meigs Line wiggled from distinct survey points (high points, etc.), see book Meigs Line and photo/commentary but others claim the photo is not of a Meigs line marker, but something the CCC did.
