Ashland City’s center stands about 590 ft above sea level. Within three miles the land runs from 380 ft to 750 ft, a difference of 370 ft: rolling country. The highest named summit within 15 miles is Ninemile Hill, about 960 ft, 14 miles south-southeast.
Under the town center the state geologic map shows Fort Payne Formation and Chattanooga Shale (chert), from the Carboniferous, 324 to 359 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 37×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

Lake on the way: Bards Lake.
970 miles of the trip are on the Mississippi.
