Kerkhoven’s center stands about 1,100 ft above sea level. Within three miles the land runs from 1,080 ft to 1,120 ft, a difference of 40 ft: nearly flat ground.
Under the town center the state geologic map shows Granitic intrusion of unknown age, from the Archean to Paleoproterozoic.
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 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.
Orthogneiss, migmatite. Age: Paleoarchean to Mesoarchean, 2.8 to 3.6 billion years old. About 11 mi of the line.
Leucocratic-granitic. Age: Neoarchean, 2.5 to 2.8 billion years old. About 8 mi of the line.
Orthogneiss. Age: Paleoarchean to Mesoarchean, 2.8 to 3.6 billion years old. About 4 mi of the line.
Granitic. Age: Archean to Paleoproterozoic. About 2 mi of the line.

A raindrop that lands in Kerkhoven reaches the Gulf of America by way of Shakopee Creek, the Chippewa, the Minnesota and the Mississippi: about 2,160 river miles.
Lake on the way: Lake Pepin.
1,750 miles of the trip are on the Mississippi.

Kerkhoven has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 1° in January. A normal year brings about 43 inches of snow; with the rain, that comes to about 28 inches of water.
On November 14 Kerkhoven normally reaches 42° and falls to 22°. The record high is 69°, in 1990; the record low −5°, in 2014. The most rain on this date, 0.40 in, fell in 2024.
