2018 Map of Isles of Shoals OE N
USGS Topo · Published 2018About this map
The vast expanse of the Atlantic Ocean dominates this coastal Maine quadrangle, highlighting the maritime hazards of the Gulf of Maine. Just off the coast of York, the map identifies specific underwater navigational features including York Ledge and the cluster of rocks known as the Triangles. These submarine landmarks represent a portion of the treacherous seafloor that has historically challenged mariners in the waters of York County. The most prominent of these hazards, Murray Rock, sits within the shoal area, illustrating the sharp transitions from open water to jagged ledges that characterize the Maine coastline. This 2018 survey serves as a focused study of the near-shore seabed and the geographical markers that define this section of the New England coast.
