About this map

Atlantic Ocean waters dominate this Knox County coastal survey, which focuses on the maritime hazards and marine geography southeast of Vinalhaven. The map records several treacherous underwater features, most notably the Junken Ledge in the northwest and the Green Island Seal Ledges in the southwest. These names reflect the local vernacular and the navigational challenges faced by mariners in these Maine waters. While largely an offshore study, the mapping of these ledges provides essential data for understanding the submerged landscape and coastal safety in the late twenty-first century.
