Coon Rapids’s center stands about 1,220 ft above sea level. Within three miles the land runs from 1,110 ft to 1,330 ft, a difference of 220 ft: 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 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 54×. 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 16 mi of the line.
Shale, sandstone, siltstone. Age: Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 million years old. About 4 mi of the line.
Shale, limestone. Age: Middle Pennsylvanian, 307 to 315 million years old. About 2 mi of the line.
Shale, siltstone. Age: Middle Pennsylvanian, 307 to 315 million years old. About 2 mi of the line.

A raindrop that lands in Coon Rapids reaches the Gulf of America by way of the Middle Raccoon, the South Raccoon, the North Raccoon, the Des Moines and the Mississippi: about 1,630 river miles.
Lake on the way: Roberts Creek.
1,330 miles of the trip are on the Mississippi.

Coon Rapids has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 10° in January. About 34 inches of rain fall in a normal year.
On November 14 Coon Rapids normally reaches 47° and falls to 27°. The record high is 71°, in 1990; the record low −10°, in 1959. The most rain on this date, 1.87 in, fell in 1926.
