Under the town center the state geologic map shows Monteagle Limestone, from the Carboniferous, 324 to 359 million years old.
The section below crosses 12 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 14×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

A raindrop that lands in South Pittsburg reaches the Gulf of America by way of the Tennessee, the Ohio and the Mississippi: about 1,430 river miles.
Lakes on the way: Guntersville Lake, White Lake (historical) and Pickwick Lake.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of South Pittsburg; river miles along the main stem, rounded.
