Noted archaeologist and naturalist Charles Conrad Abbot (1843 – 1919) made his home at the edge of the Marshlands for many years.  In 1872, he reported finding man-made implements in the Trenton glacial gravels on his farm.

This discovery sparked an international debate and forty year controversy concerning the antiquity of man in the New World.  The controversy made Abbott Farm one of the best known archaeological sites in eastern North America to scientists on two continents, and to the American public.  More than 100 books and articles were published about the site.  It is one of the most significant prehistoric archaeological sites in the eastern United States.  Archaeological studies are still being conducted today.

Because of its archaeological importance, the area that includes much of the Marshlands was designated the Abbott Farm National Historic Landmark by the United States Department of Interior in 1976.
