 The cornerstone was erected by commissioners appointed by the two states to survey the boundary between the western termination of the boundary line which had been run in 1764 and to the southeast corner of Catawba lands.The cornerstone is an uneven, rectangular, upright metamorphosed igneous stone marker approximately two feet high.The top part of the cornerstone, which contains the engraved notations, "N.C." and "S.C." was broken off when a car hit the marker in 1977.
