|This NYT article gives a slideshow about a Natural history of Manhattan over the past 400 years. The new map-based exhibit opened at the Museum of the City of New York. It is called, "Mannahatta/Manhattan: A Natural History of New York City." The exhibit consists of historical accounts, maps and computer models that explore the ecology of Manhattan from the time before it became a city.|
The project has also its own website HERE and a book. This is a pretty good multi-media site that gives layers of meaning to those who now live in Manhattan.
