Timmonsville’s center stands about 160 ft above sea level. Within three miles the land runs from 120 ft to 190 ft, a difference of 70 ft: gently rolling country.
Under the town center the state geologic map shows Bear Bluff Formation (sand, limestone), from the Tertiary, 2.6 to 66 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. 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 Timmonsville reaches the Atlantic Ocean by way of Sparrow Swamp, the Lynches, Clark Creek, the Great Pee Dee, Schooner Creek and the Waccamaw: about 120 river miles.
