Jonesboro’s center stands about 850 ft above sea level. Within three miles the land runs from 800 ft to 890 ft, a difference of 90 ft: gently rolling country.
Under the town center the state geologic map shows Pleasant Mills Formation (dolostone, limestone), from the Silurian, 422 to 445 million years old.
The section below crosses 2 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.
Dolostone, limestone. Age: Silurian, 422 to 445 million years old. About 13 mi of the line.
Limestone, dolostone. Age: Silurian, 422 to 445 million years old. About 11 mi of the line.

A raindrop that lands in Jonesboro reaches the Gulf of America by way of Back Creek, the Mississinewa, the Wabash, Big Bayou, the Wabash River Old Channel, the Old Channel Wabash, the Ohio and the Mississippi: about 1,510 river miles.
Lake on the way: Mississinewa Lake.
970 miles of the trip are on the Mississippi.
