Pollen analysis was done on a core through a linear mound formerly identified as a 1777 British earthwork at Saratoga National Historical Park. Documents indicate that the British earthwork was built in a forest in a sparsely settled region. Pollen data record a 71-year reforestation sequence under the mound, indicating that it cannot be a Revolutionary War earthwork.
