Where: Iowa · approx. 41.66, -91.53 (vicinity only)
Why this spot: 1880s+ Sanborn-mapped town on Iowa River at the first state capital; historic dam, mill, and university-town riverfront
What turns up: Union Brewery and other brewery blob-tops, local stoneware pottery, Iowa City soda Hutchinsons, embossed druggists, and early capital-era domestic glass
Access: Gray area.
The Iowa River here is generally not treated as navigable, so the bed below the ordinary high-water mark may still be state-claimed public trust; confirm before removing anything and note much of the channel abuts private and university land needing permission. Iowa law protects archaeological sites and unmarked burials.
