"S" is for South Carolina-North Carolina Border
"S" is for South Carolina-North Carolina border. In 1735 the two colonies appointed a joint boundary commission. From a point thirty miles south of the Cape Fear River a straight line was to run northwest until it reached the 35th parallel—and from there a straight line would run to the Pacific Ocean. Because of surveying errors, South Carolina’s northern boundary was eleven miles south of where it should have been. To correct this mistake, the boundary was extended seventeen miles north of the 35th parallel and westward to the crest of the Saluda Mountains. However, for years there was disagreement as to the exact location of the boundary line. In 2017, a joint commission from both states finally agreed to the verification of a modern survey of the border—ending centuries of uncertainty.
