Where: Wisconsin · approx. 43.75, -87.71 (vicinity only)
Why this spot: 1880s+ Sanborn-mapped town on Lake Michigan harbor and the Sheboygan River
What turns up: Local brewery blob-tops, Hutchinson and gravitating-stopper sodas, mineral-water and ginger beer bottles, druggist bottles, and lakefront fishing and shipping refuse.
Access: Gray area.
Wisconsin holds the bed of the Great Lakes below the ordinary high-water mark in public trust, so removing historic artifacts from the submerged lakebed is restricted and generally not permitted without state authorization; the townsite banks, beaches above the line, and uplands are usually privately owned and require the landowner's permission; state law also protects archaeological sites and unmarked burials.
