Where: Iowa · approx. 42.5, -94.17 (vicinity only)
Why this spot: 1880s+ Sanborn-mapped town on Des Moines River gypsum-and-clay town on the upper river; historic mill and quarry landings
What turns up: Clay-district potteries and tile-works stoneware, gypsum-plant refuse, brewery and soda bottles, embossed druggists along the river bench
Access: Gray area.
The Des Moines River here is smaller and navigability may be contested, so treat the bed below the ordinary high-water mark as potential state public-trust land and confirm status before removing anything. Riverbank and townsite uplands are usually private and need the owner's permission. Iowa law protects archaeological sites and unmarked burials.
