New York in an Alternate Ice Age

The geographical features that make New York stand out from any other of the United States--Long Island, the huge boulders scattered in the city and the Hudson River, deep enough for barges to pass through without problem--are possible because New York was the furthest south that the ice of the Late Pleistocene extended from the Arctic.

Now, in this alternate ice age, lobes of ice extended further southwards, to Washington DC, Virginia and Chesapeake Bay. Would we still find the distinctive shape of Long Island? Or would the more extensive ice alter the geography of the New York cityscape?
