Summary
Abstract: These maps are based on 11,700 fossil pollen samples and 1744 modern pollen
samples. Twenty-one pollen taxa were included in analyses: Alnus, Fraxinum,
Populus, Tilia, Fagus, Betula, Ulmus, Abies, Celtis, Corylus, Tsuga, Carya,
Ostrya/Carpinus, Quercus, Pinus, Prairie, Cyperaceae, Picea, Liquidambar,
Platanus, and Juglans.

Analog/no anolog vegetation types were assigned to a 100x100km at 1000 year
intervals using a three dimensional, time-space, interpolation scheme. To
generate maps the paleocoast line/ocean and Laurentide Ice Sheet were overlain
to mask out appropriate portions of equal area grid boxes.

Age estimates are based on uncalibrated radiocarbon dates.
