The tree standing here is younger than most of the people who come to see it. The Mercer Oak that made this field famous was a white oak of about three hundred years, standing near the spot where General Hugh Mercer was mortally wounded in the Battle of Princeton on 3 January 1777, and it went down in high winds in March 2000. What grows there now came out of its own acorn. An arborist planted an eight foot sapling in the remains of the parent's stump; the Princeton Battlefield Society dates that planting to 2001, while other accounts say only that it happened soon after the fall. So this is a young tree on old ground: a slim white oak alone in the middle of an open field, photographed at the spot as recently as 2024, and about twenty five years into a job the last one held for three centuries. Nobody visiting today will see it finished. The field around it is the reason to make the walk. Princeton Battlefield is a National Historic Landmark, free and open daily, and the oak marks the place rather than competing with it.
The line is our estimate of how much there is to see, not a measurement. Typical for this species where this tree stands; exact weeks shift with the year.
