Kimball’s center stands about 1,570 ft above sea level. Within three miles the land runs from 1,430 ft to 2,530 ft, a difference of 1,100 ft: steep hill country. The highest named summit within 15 miles is Pilot Knob, about 3,250 ft, 14 miles east-northeast.
Under the town center the state geologic map shows Pocahontas Formation (sandstone), from the Carboniferous, 299 to 324 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 9×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 19 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 6 mi of the line.

A raindrop that lands in Kimball reaches the Gulf of America by way of Elkhorn Creek, the Tug Fork, the Ohio and the Mississippi: about 1,800 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Kimball; river miles along the main stem, rounded.
Kimball has a humid subtropical climate. Summer afternoons average 85° in July; winter nights fall to about 22° in January. About 49 inches of rain fall in a normal year.
