A National Historic Landmark since 1994, this quiet wooded mini-park marks the marl pit where William Parker Foulke excavated the Hadrosaurus foulkii skeleton in 1858, the discovery that proved dinosaurs were real to a skeptical public. Two small markers and a bench sit above the ravine where the actual dig took place; it's not a polished attraction, just a genuine historic site families can stand in and imagine 1858. Wear sneakers, as the path is informal and can be muddy, and pair the visit with the Academy of Natural Sciences in Philadelphia to see where the bones ended up.
