Moundville’s center stands about 180 ft above sea level. Within three miles the land runs from 100 ft to 360 ft, a difference of 260 ft: rolling country. The highest named summit within 15 miles is Sand Mountain, about 480 ft, 11 miles northeast.
Under the town center the state geologic map shows Alluvial, coastal and low terrace deposits (sand), from the Holocene, less than 12,000 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 43×. 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 Moundville reaches Mobile Bay and the Gulf of America by way of Elliotts Creek, the Black Warrior, the Tombigbee and the Mobile: about 310 river miles.
170 miles of the trip are on the Tombigbee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Moundville; river miles along the main stem, rounded.
