Jonesboro’s center stands about 230 ft above sea level. Within three miles the land runs from 140 ft to 340 ft, a difference of 200 ft: gently rolling country.
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 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.

Sand, clay. Age: Eocene, 34 to 56 million years old. About 7 mi of the line.
Clay. Age: Holocene, less than 12,000 years old. About 5 mi of the line.
Clay, marl. Age: Eocene, 34 to 56 million years old. About 3 mi of the line.

A raindrop that lands in Jonesboro reaches the Gulf of America by way of the Dugdemona, the Little River, the Black River, the Red River, the Atchafalaya and the Lower Atchafalaya: about 380 river miles.
Lake on the way: Catahoula Lake.
100 miles of the trip are on the Atchafalaya.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Jonesboro; river miles along the main stem, rounded.
