USGS Topo · Published 2021About this map
Atlantic Ocean waters dominate this nautical survey, capturing the hazardous sub-surface topography off the coast of Maine. The map identifies specific maritime dangers such as York Ledge, a prominent formation situated in the northern reaches of the sheet. Further south, the seafloor is marked by the Triangles and Murray Rock, features essential for navigation and of significant interest to local maritime historians and divers. This sheet focuses almost exclusively on these offshore landmarks, providing a clear view of the underwater landscape as it was documented in 2021 without the distraction of coastal development or terrestrial landmarks.
