2014 Map of Machias Seal Island

About this map

Machias Seal Island and its surrounding waters define this coastal survey of the far eastern reaches of Maine. Located in the open Atlantic Ocean, this small landmass and the nearby North Rock represent significant navigational markers for the region's maritime history. The map also identifies North Shoal, a submarine feature critical to those working these waters. Given its location and the presence of these isolated geographic features, the sheet provides essential documentation for researchers studying maritime boundaries and the topographical character of the Gulf of Maine’s outer islands during the early 21st century.
