These tracks once hosted the Eastern RR from Boston to Portsmouth. Today just south of here is a way to cross the Hampton Marsh on foot, away from the traffic of Rte 1.
We took GPS readings beneath the high-tension wires of the Seabrook Nuclear Power Plant. We added a photo to give you a visual to the area in which our cache (a bison tube) is located.
This cache is a bit off the beaten path, as evidenced by the higher terrain rating. Be careful, and happy hunting!
