Fair Oaks’s center stands about 1,120 ft above sea level. Within three miles the land runs from 950 ft to 1,190 ft, a difference of 240 ft: rolling country. The highest named summit within 15 miles is Kennesaw Mountain, about 1,780 ft, 4 miles north-northwest.
Under the town center the state geologic map shows Biotitic Gneiss / Mica Schist/ Amphibolite (amphibolite, biotite-gneiss, mica-schist), from the Precambrian to Paleozoic.
The section below crosses 11 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 23×. 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 Fair Oaks reaches the Gulf of America by way of Nickajack Creek, the Chattahoochee and the Apalachicola: about 410 river miles.
Lakes on the way: Walter F George Reservoir, West Point Lake and Bartletts Ferry Lake.
110 miles of the trip are on the Apalachicola.
