The River That Isn’t A River
The East River of New York is where you’ll find our abandoned island but what you may not know is that the East River isn’t a river at all. It’s a tidal estuary and is purely salt rather than fresh water.
It runs from Long Island Sound at its northern tip and stops at Upper New York Bay at the southernmost point. For a long period of time it was the heart of the maritime trade in New York and it was once the busiest sea lane in the city. This is, of course, no longer the case and the East River is far less busy today.
