Editing Sag Harbor, New York (section)

=== Topography ===
The majority of Sag Harbor lies on a flat, sandy coastal plain which makes up much of southern Long Island and extends along the southern coast of the island. It is the remains of a glacial moraine. Small hills rise up from the shore at about {{convert|0.3|mi}} inland. Knolls and hills are dominated mostly by Red and Scarlet [[oak tree]]s, which are interspersed with pitch and white pines. On many of the protected bay shores, wetlands and dune ecosystems dominate the land.
