Cairo, Alexander County Ohio and Mississippi confluence port

BOTTLE DIGGING GRAY AREA CONFIRMED

Where: Illinois · approx. 37.01, -89.18 (vicinity only)

Why this spot: 1880s+ Sanborn-mapped town on Ohio River

What turns up: Steamboat and wharfboat-era ceramics, embossed bottles from cotton and lumber trade saloons and hotels, and stoneware along the levees at the confluence

Access: Gray area.

In Illinois the beds of the Ohio and Mississippi below the ordinary high-water mark are 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.
