The English elm growing beside an apartment complex on the east side of St. Nicholas Avenue at 163rd Street was probably planted on the estate of the nearby Morris Jumel Mansion. George Washington stood here on the night of September 21, 1776 to watch the fire set by American rebels that destroyed much of New York City.

‘Cloning’ comes to trees in new preservation push
To keep natural history alive, a New York program tries grafting ancient giants.

NEW YORK — For generations, the towering English Elm has presided over the intersection of 163rd St. and St. Nicholas Ave., in the Washington Heights neighborhood of upper Manhattan. Fifty-three blocks from the tip of Central Park, the “dinosaur,” as residents fondly call it, might have served as a natural gateway for Gen. George Washington, rumored to have passed under its boughs at the onset of the Revolutionary War.

THE DINOSAUR
Our sketch tour will start at 163rd Street and St. Nicholas Avenue where we will sketch The Dinosaur, an English Elm standing 110’.  The tree stood on what was the Morris-Jumel estate.  On November 16, 1776, nearly 238 years ago, George Washington stood under this tree and watched the tides of battle turn against his forces.  At the battle of Fort Washington New York City fell to the British and remained in English control until the end of the civil war.  Today this tree stands inconspicuously in the middle of a typical NYC street, a giant witness to history.
