The Everett Libby Ferry route bisects the vast maritime landscape of the Atlantic Ocean in this coastal survey of Knox County. This navigation corridor serves as a primary link between mainland Maine and its outlying islands, cutting a straight path through open water. Along the southern edge of the sheet, the rocky outposts of the Petit Manan National Wildlife Refuge emerge, including Two Bush Island and the landform at Northeast Point. These small islands and hazard markers like Whaleback and Seal Ledges define the treacherous approach for local mariners. The map highlights the isolated nature of these mid-coast features, where named maritime hazards such as Junken Ledge and Green Island provide essential orientation in an environment dominated by the sea.
