Illinois-Indiana State Line Boundary Marker - U.S. Historic Survey Stones and Monuments on Waymarking.com

On September 4, 2002, this sandstone obelisk was designated a Chicago Landmark. One of the oldest structures in the city (being one of few to survive both the Great Fire and the ravages of time), this marker sits atop the Illinois-Indiana state line, as one of (if not the) northernmost marked portion of the boundary. The marker, originally placed in 1833, was moved in 1988 191.09 feet north of its former position, but still straddles the state line.

The obelisk is south of Avenue G near the entrance to the State Line Generating Plant.
