Knapp’s center stands about 930 ft above sea level. Within three miles the land runs from 890 ft to 1,220 ft, a difference of 330 ft: rolling country. The highest named summit within 15 miles is Otteson Bluff, about 1,280 ft, 8 miles east.
Under the town center the state geologic map shows Cambrian, undivided (sandstone), from the Cambrian, 487 to 542 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 39×. 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. Age: Cambrian, 487 to 542 million years old. About 14 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 10 mi of the line.

A raindrop that lands in Knapp reaches the Gulf of America by way of Wilson Creek, the Red Cedar, the Chippewa and the Mississippi: about 1,800 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Knapp; river miles along the main stem, rounded.
Knapp has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 4° in January. A normal year brings about 41 inches of snow; with the rain, that comes to about 34 inches of water.
On November 14 Knapp normally reaches 43° and falls to 24°. The record high is 70°, in 1990; the record low 4°, in 1996. The most rain on this date, 0.63 in, fell in 2010.
Normals 1991–2020 and records since 1948 at Menomonie, 9 miles southeast, 140 ft lower. NOAA, through RCC-ACIS.
