Cedar Grove Colony’s center stands about 1,610 ft above sea level. Within three miles the land runs from 1,530 ft to 1,640 ft, a difference of 110 ft: gently rolling country.
Under the town center the state geologic map shows Pierre Shale (shale, bentonite), from the Late Cretaceous, 66 to 100 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.
Shale, bentonite. Age: Late Cretaceous, 66 to 100 million years old. About 16 mi of the line.
Chalk, marlstone, shale. Age: Late Cretaceous, 66 to 100 million years old. About 9 mi of the line.

A raindrop that lands in Cedar Grove Colony reaches the Gulf of America by way of Platte Creek, the Missouri and the Mississippi: about 2,110 river miles.
Lakes on the way: Lake Francis Case and Lewis and Clark Lake.
1,170 miles of the trip are on the Mississippi.

Cedar Grove Colony has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 10° in January. A normal year brings about 42 inches of snow; with the rain, that comes to about 24 inches of water.
On November 14 Cedar Grove Colony normally reaches 47° and falls to 25°. The record high is 78°, in 1953; the record low −20°, in 1959. The most rain on this date, 0.80 in, fell in 1928.
