State Line City’s center stands about 720 ft above sea level. Within three miles the land runs from 640 ft to 730 ft, a difference of 90 ft: gently rolling country.
Under the town center the state geologic map shows Raccoon Creek Group (shale, sandstone), from the Carboniferous, 299 to 324 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 12 mi of the line.
Shale, sandstone, coal. Age: Middle Pennsylvanian to Late Pennsylvanian, 304 to 315 million years old. About 7 mi of the line.
Shale, sandstone. Age: Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 million years old. About 4 mi of the line.
Shale, limestone. Age: Late Pennsylvanian, 304 to 307 million years old. About 1 mi of the line.

A raindrop that lands in State Line City reaches the Gulf of America by way of Stony Creek, the Vermilion, Big Bayou, the Wabash River Old Channel, the Old Channel Wabash, the Ohio and the Mississippi: about 1,380 river miles.
970 miles of the trip are on the Mississippi.
