A 3D paleo-environmental reconstruction of prehistoric topography and habitat of the formally exposed New Jersey Meadowlands as it was before being inundated by rising sea levels ca. 2000-3000 BP. The digital terrain model, or 3D surface-mesh model, is derived from georeferenced 1865 US Army survey of bathymetry and mud-depth readings in the Hackensack Basin. The environmentally accurate 3D prehistoric tree and plant cover is identified from radiocarbon-dated pollen cores (see Grossman 1992, 1994, 1995 2003, 2006 & 2007 in Hunter Research 2006 & 2007a for additional discussion of the logistical and planning utility of these pre-landfill reconstructions; see Grossman 2007a for discussion and background).)
