About this map

Long Island Railroad corridors define the development of central Suffolk County, with the Main Line and Montauk Division carving paths through a landscape of coastal harbors and interior heights. The northern shore is deeply indented by maritime features like Huntington Bay and Port Jefferson Harbor, while the interior rises into the Dix Hills and Half Hollow Hills. Prominent social and institutional landmarks of the era are visible, including the St. Dominic Convent near the western boundary and the expansive State Hospital grounds near Kings Park.

Southward, the map details the intricate waterways of Great South Bay, shielded from the Atlantic Ocean by the narrow barrier of Oak Island Beach. Waterways such as the Nissequogue River and Connetquot River drain the glacial terrain into the sounds and bays. The presence of numerous Life Saving Stations, such as Eatons Pt. L.S.S., underscores the maritime risks and coastal activity at the start of the century.
