Where: Iowa · approx. 42.79, -91.1 (vicinity only)
Why this spot: 1880s+ Sanborn-mapped town on Mississippi River German colony town at Lock and Dam 10; historic button and clamming shore
What turns up: German-community brewery blob-tops, soda Hutchinsons, embossed druggists, pearl-button shell waste, and salt-glaze stoneware along the riverfront
Access: Gray area.
The Mississippi is navigable, so the bed below the ordinary high-water mark is state public-trust land with restrictions on removing historic artifacts. Riverbank and townsite uplands are usually private and require the owner's permission. Iowa law protects archaeological sites and unmarked burials.
