The Mannahatta Project allows you to enter in a street address and see what that location may have looked like in 1609. You can then click on the virtual thumbtack on the map and get a popup window (like this one for 151 E 25th St) that will detail:
- what wildlife probably lived there (common names and scientific names are provided)
- any uses of the land there by the Lenape
- what the topography was like
- what the area is like now (you get a link to the OASIS map for the location; here's the link provided for 151 E 25th St)
You can drag the map around on your screen, zoom in and out, and even overlay the modern street grid.
