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.
