Farmington’s center stands about 530 ft above sea level. Within three miles the land runs from 430 ft to 620 ft, a difference of 190 ft: gently rolling country. The highest named summit within 15 miles is Bonds Mountain, about 720 ft, 14 miles east-southeast.
Under the town center the state geologic map shows Coffee sand (sand, clay), from the Late Cretaceous, 66 to 100 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 61×. 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 Farmington reaches the Gulf of America by way of Clear Creek, the Tuscumbia River Canal, the Hatchie, Porters Creek, Cypress Creek and the Mississippi: about 990 river miles.
800 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Farmington; river miles along the main stem, rounded.
