Sioux Rapids’s center stands about 1,290 ft above sea level. Within three miles the land runs from 1,250 ft to 1,420 ft, a difference of 170 ft: gently rolling country.
Under the town center the state geologic map shows Dakata and Windrow Formations (sandstone, shale), from the Early Cretaceous to Late Cretaceous, 94 to 113 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.
Sandstone, shale. Age: Early Cretaceous to Late Cretaceous, 94 to 113 million years old. About 20 mi of the line.
Shale, limestone, dolostone. Age: Late Devonian, 374 to 384 million years old. About 4 mi of the line.

A raindrop that lands in Sioux Rapids reaches the Gulf of America by way of the Little Sioux, the Missouri and the Mississippi: about 1,970 river miles.
1,170 miles of the trip are on the Mississippi.
