Where: New Hampshire · approx. 43.21, -71.54 (vicinity only)
Why this spot: 1870s+ Sanborn-mapped town on Merrimack River
What turns up: State-capital and coach-building era refuse: aqua and amber bottles, local soda and druggist bottles, redware and ironstone sherds, clay pipes, and buttons and coins in privy pits and dumps behind Main Street lots and the old riverfront near the Abbot-Downing works.
Access: Gray area.
New Hampshire framing: the bed of the navigable Merrimack River below the ordinary high-water mark is state-owned and removing historic artifacts there is restricted. Riverbank and downtown uplands are private and need the owner's permission. State law protects archaeological sites and unmarked burials.
