The
Hudson River is a river that flows from north to south primarily through eastern
New York in the United States. The river originates in the
Adirondack Mountains of
Upstate New York, flows through the
Hudson Valley, and eventually drains into the
Atlantic Ocean, between
New York City and
Jersey City. The river serves as a political boundary between the states of New Jersey and New York, and further north between New York
counties. The lower half of the river is a
tidal estuary occupying the Hudson
Fjord, which formed during the most recent period of North American
glaciation, estimated at 26,000 to 13,300 years ago. Tidal waters influence the Hudson's flow from as far north as
Troy.
