New Market’s center stands about 770 ft above sea level. Within three miles the land runs from 710 ft to 1,260 ft, a difference of 550 ft: hilly country. The highest named summit within 15 miles is Johnson Top, about 1,910 ft, 8 miles northeast.
Under the town center the state geologic map shows Fort Payne Chert (limestone, siltstone), 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 17×. 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 New Market reaches the Gulf of America by way of Rodgers Branch, the Mountain Fork, the Flint, the Tennessee, the Ohio and the Mississippi: about 1,400 river miles.
Lakes on the way: Guntersville Lake, White Lake (historical) and Pickwick Lake.
970 miles of the trip are on the Mississippi.
