Tazewell’s center stands about 460 ft above sea level. Within three miles the land runs from 430 ft to 650 ft, a difference of 220 ft: rolling country.
Under the town center the state geologic map shows Cusseta Sand, from the Cretaceous, 66 to 145 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 50×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Clay, sand. Age: Cretaceous, 66 to 145 million years old. About 8 mi of the line.
Sand. Age: Cretaceous, 66 to 145 million years old. About 6 mi of the line.
Sand. Age: Cretaceous, 66 to 145 million years old. About 6 mi of the line.
Sand, clay. Age: Cretaceous, 66 to 145 million years old. About 3 mi of the line.

From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Tazewell reaches the Gulf of America by way of Buck Creek, the Flint and the Apalachicola: about 310 river miles.
170 miles of the trip are on the Flint.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Tazewell; river miles along the main stem, rounded.
