Why this spot: 1880s+ Sanborn-mapped town on Rock River
What turns up: Soda and beer bottles, foundry slag, and stoneware near the Rock River dam and the old riverfront commercial blocks
Access: Gray area.
In Illinois the bed of the Rock River below the ordinary high-water mark is state-owned public land where removing historic artifacts is restricted. The townsite banks and uplands are usually private and need the landowner's permission, and state law protects archaeological sites and unmarked graves.
