About this map

The Atlantic Ocean dominates this maritime survey off the coast of Knox County, Maine. This specific area of the outer Maine coastline is defined by underwater and semi-exposed navigational hazards. To the northwest, Junken Ledge marks a significant subsurface feature for mariners navigating these waters. In the southwestern corner, the Green Island Seal Ledges represent a collection of rock formations that are critical landmarks for both local wildlife and vessel pilots. The map highlights the sparse, nautical character of the region where the sea meets these isolated rocky outcroppings, providing essential data for those studying the coastal geography and hydrography of the Gulf of Maine in the early 21st century.
