Queens County is in the western part of Long Island and includes a few smaller islands, most of which are in Jamaica Bay and form part of Gateway National Recreation Area, which is in turn one of the National Parks of New York Harbor.
The Rockaway Peninsula sits between Jamaica Bay and the Atlantic Ocean. The western and northern edge of the borough is defined a watery continuum made up of Newtown Creek which flows into the tidal estuary known as the East River, which includes the associated Flushing Bay and Flushing River. The East River opens into Long Island Sound. The mid-section of Queens is crossed by the Long Island straddling terminal moraine created by the Wisconsin Glacier. This feature evolved into a land use pun due to the siting of many cemeteries.
The tallest tree in the New York metropolitan area, called the Queens Giant, is also the oldest living thing in the New York metro area. It is located in northeastern Queens, and is 450 years old and 132 feet (40 m) tall as of 2005.
