The N.C. Department of Natural and Cultural Resources, which manages the North Carolina Highway Historical Marker Program, requests the public’s help in locating a missing historical marker. The marker was located at US 70 at Eno River bridge northwest of Hillsborough. It identified Hart’s Mill, which was located outside of present-day Hillsborough and was the site of a large, well-publicized meeting of Regulators opposed to British rule in 1766.
