Brandon’s center stands about 500 ft above sea level. Within three miles the land runs from 330 ft to 510 ft, a difference of 180 ft: gently rolling country.
Under the town center the state geologic map shows Vicksburg group and Chickasawhay limestone, from the Oligocene, 23 to 34 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 54×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone. Age: Oligocene, 23 to 34 million years old. About 10 mi of the line.
Clay. Age: Eocene, 34 to 56 million years old. About 6 mi of the line.
Sand, clay. Age: Oligocene, 23 to 34 million years old. About 4 mi of the line.
Sand. Age: Miocene, 5.3 to 23 million years old. About 4 mi of the line.

A raindrop that lands in Brandon reaches the Gulf of America by way of Terrapin Skin Creek, Richland Creek and the Pearl: about 310 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Brandon; river miles along the main stem, rounded.
