This is an original antique map from the U.S. Coast Survey, dated 1868. Titled "SKETCH D SHOWING THE PROGRESS OF THE SURVEY IN SECTION No. IV FROM 1850 TO 1868," it details the extensive surveying efforts along the North Carolina coast. The map highlights various survey stations, hydrographic soundings, and coastal features, providing a fascinating glimpse into the meticulous work of the U.S. Coast Survey under Superintendent A.D. Bache. This piece would be a significant addition to any collection of historical maps, maritime charts, or North Carolinaiana. The map shows areas including Newbern, Core Sound, Ocracoke Inlet, and Cape Lookout.
