N.C. Gen. Stat. § 14-147
If any person, firm or corporation shall knowingly remove, alter or deface any landmark in anywise whatsoever, or shall knowingly cause such removal, alteration or defacement to be done, such person, firm or corporation shall be guilty of a Class 2 misdemeanor. This section shall not apply to landmarks, such as creeks and other small streams, which the interest of agriculture may require to be altered or turned from their channels, nor to such persons, firms or corporations as own the fee simple in the lands on both sides of the lines designated by the landmarks removed, altered or defaced. Nor shall this section apply to those adjoining landowners who may by agreement remove, alter or deface landmarks in which they alone are interested.
