82° on Nov. 15, 2025, the hottest reading for this week of the year since 1894. Next is 81° in 2016.
Campbell’s center stands about 2,040 ft above sea level. Within three miles the land runs from 1,970 ft to 2,100 ft, a difference of 130 ft: gently rolling country.
Under the town center the state geologic map shows Pierre Shale, from the Late Cretaceous, 66 to 100 million years old.
The section below crosses 3 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. Age: Late Cretaceous, 66 to 100 million years old. About 15 mi of the line.
Limestone, shale. Age: Late Cretaceous, 66 to 100 million years old. About 8 mi of the line.
Siltstone-mudstone, conglomerate-sandstone. Age: Miocene, 5.3 to 23 million years old. About 1.0 mi of the line.

A raindrop that lands in Campbell reaches the Gulf of America by way of the Little Blue, the Big Blue, the Kansas, the Missouri and the Mississippi: about 1,950 river miles.
Lake on the way: Tuttle Creek Lake.
1,170 miles of the trip are on the Mississippi.

Campbell has a hot-summer humid continental climate. Summer afternoons average 91° in July; winter nights fall to about 12° in January. A normal year brings about 19 inches of snow; with the rain, that comes to about 26 inches of water.
On November 14 Campbell normally reaches 53° and falls to 25°. The record high is 79°, in 1999; the record low −3°, in 1986. The most rain on this date, 1.14 in, fell in 1926.
