Lake Ontario dominates this offshore view of the Great Lakes shoreline in the early 21st century. This specific quadrangle covers a vast expanse of open water, illustrating the deep hydraulic context of the Lake Ontario basin north of the New York coast. As a modern digital composite, the map documents the precise bathymetric and hydrographic state of the lake as recorded by the U.S. Geological Survey in 2013, providing a clean spatial reference for the maritime boundaries and aquatic geography of the region.
