This slideshow from The New Yorker features historic maps and computer-recreations to show how Manhattan may have looked before the arrival of Europeans.
"Eric Sanderson, a landscape ecologist at the Wildlife Conservation Society, is trying to determine exactly how Manhattan-or Mannahatta, 'land of many hills,' as some scholars have translated the name used by the Lenape people who inhabited it-looked before the arrival of Europeans. The project is set for completion in 2009, the quadricentennial of Henry Hudson's 1609 visit to the island, and will include a coffee-table book, interactive exhibits, a series of printed street guides, and a three-dimensional virtual re-creation."
