The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 41×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 12 mi of the line.
Chert. Age: Carboniferous, 324 to 359 million years old. About 12 mi of the line.

A raindrop that lands in White Bluff reaches the Gulf of America by way of Turnbull Creek, the Harpeth, the Cumberland, the Ohio and the Mississippi: about 1,230 river miles.
Lake on the way: Bards Lake.
970 miles of the trip are on the Mississippi.
