Where: New Hampshire · approx. 43.26, -70.86 (vicinity only)
Why this spot: 1890s+ Sanborn-mapped town on Salmon Falls River, the New Hampshire and Maine boundary river
What turns up: Great Falls Manufacturing mill refuse: aqua medicine and beer bottles, stoneware and ironstone shards, clay pipe fragments, and buttons and small coins in privy pits and back-lot dumps along the Salmon Falls gorge and Main Street tenement rows.
Access: Gray area.
New Hampshire framing: the bed of the navigable Salmon Falls River below the ordinary high-water mark is state-owned, and it also forms the interstate boundary, so removing historic artifacts there is restricted. Mill-yard and riverbank uplands are private and need the owner's permission. State law protects archaeological sites and unmarked burials.
