What Travellers Say
Reviews Summary
Visitors find the Arc Corner Monument a unique and interesting geographic marker, especially for its novelty of straddling two states. The surrounding White Clay Creek State Park offers pleasant hiking, though some note parking can be a challenge and the monument itself is understated.
"A short hike into White Clay Creek State Park brings you to the Arc Corner Monument Stone. Set in place in 1892, it marks the location where the northern border between Delaware and Pennsylvania, the “arc,” connects with the east-west straight line border. It’s nothing dramatic, and is of interest mainly to map and geographic nerds, but it is a significant marker. It’s also a pretty hike."
Jeff Quiggle
"A historic boundary easily accessible either through a hike or by parking at a pull-out area located a little past the monument on the north side of Hopkins Road."
Ian Lefkowitz
"The Arc Corner Monument Stone was erected in 1892, and represents the point where the 12-mile circle intersects the "Top of The Wedge Line", an eastern extension of the north line of the Mason Dixon Line.
The monument can be accessed via the trails of the White Clay Creek Preserve, although I parked along Hopkins Road and made the short trek into the woods."
