Where: Virginia · approx. 38.8, -77.05 (vicinity only)
Why this spot: 1880s+ Sanborn-mapped town on Potomac River (tidal)
What turns up: 18th-century tobacco port on the Potomac: rich privy and waterfront-fill dumps with pontiled medicines, blob sodas, blackglass, stoneware, clay pipes, buttons, and coins beneath Old Town lots and along the river's made land.
Access: Gray area.
The Potomac River bottom is public-trust land (the Virginia-Maryland boundary and federal interests make jurisdiction complex) where taking historic artifacts is restricted; Old Town lots on the Sanborn footprint are private and need the owner's permission. State law protects archaeological sites, and much of Alexandria's ground is under active professional archaeological oversight.
