Arkansas City’s center stands about 140 ft above sea level. Within three miles the land runs from 100 ft to 180 ft, a difference of 80 ft: gently rolling country.
Under the town center the state geologic map shows Alluvium - Alluvial deposits of local streams or of overbank flow of major streams (coarse-detrital, fine-detrital), from the Holocene, less than 12,000 years old.
The section below crosses 3 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.
Coarse-detrital, fine-detrital. Age: Holocene, less than 12,000 years old. About 13 mi of the line.
Coarse-detrital, fine-detrital. Age: Holocene, less than 12,000 years old. About 6 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 5 mi of the line.

A raindrop that lands in Arkansas City reaches the Gulf of America by way of the Bayou Macon, the Tensas, the Black River, the Red River, the Atchafalaya and the Lower Atchafalaya: about 450 river miles.
200 miles of the trip are on the Bayou Macon.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Arkansas City; river miles along the main stem, rounded.
