Dunlap’s center stands about 720 ft above sea level. Within three miles the land runs from 690 ft to 2,180 ft, a difference of 1,490 ft: steep hill country. The highest named summit within 15 miles is Ross Mountain, about 2,350 ft, 11 miles west.
Under the town center the state geologic map shows Ridley Limestone, from the Ordovician, 445 to 487 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 12×. 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 Dunlap reaches the Gulf of America by way of Coops Creek, the Sequatchie, the Tennessee, the Ohio and the Mississippi: about 1,480 river miles.
Lakes on the way: Guntersville Lake, White Lake (historical), Pickwick Lake and Cummings 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 Dunlap; river miles along the main stem, rounded.
