None of the trees inside this fence were standing in 1863. The National Park Service says so plainly on its own page for the site, and it is the first thing to know before you walk up to what may be the most famous clump of trees at Gettysburg. What stood here on 3 July 1863 was a small clump of bushes and trees on Cemetery Ridge. Confederate planners chose it as the visual target for Pickett's Charge, the point the whole assault was aimed at. The attack reached it, and that is as close as it came to breaking the Union line. The place has been called the High Water Mark ever since, and the monument of that name stands beside it. So the trees are successors, not survivors. Today it is roughly half a dozen large trees, mostly chestnut oak, inside a low iron fence put up in 1887 to keep souvenir hunters from carrying the copse away. The count and the full species mix are approximate, because the sources we checked give neither exactly, and none of the trees has a published age. Why map it at all, then? Because this is exactly where people come to stand. The copse was the landmark the charge aimed at, and it still marks the spot. The age of the wood is beside the point; the place is not. It is free, and a short walk from Hancock Avenue.
