Underwood’s center stands about 1,070 ft above sea level. Within three miles the land runs from 1,050 ft to 1,290 ft, a difference of 240 ft: rolling country.
Under the town center the state geologic map shows Kansas City Group (limestone, shale), from the Late Pennsylvanian, 299 to 307 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 55×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone, shale. Age: Late Pennsylvanian, 299 to 307 million years old. About 15 mi of the line.
Limestone, shale. Age: Middle Pennsylvanian to Late Pennsylvanian, 299 to 315 million years old. About 5 mi of the line.
Sandstone, shale. Age: Early Cretaceous to Late Cretaceous, 94 to 113 million years old. About 4 mi of the line.

A raindrop that lands in Underwood reaches the Gulf of America by way of Mosquito Creek, the Missouri and the Mississippi: about 1,780 river miles.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Underwood; river miles along the main stem, rounded.
Underwood has a hot-summer humid continental climate. Summer afternoons average 88° in July; winter nights fall to about 15° in January. A normal year brings about 27 inches of snow; with the rain, that comes to about 32 inches of water.
On November 14 Underwood normally reaches 51° and falls to 31°. The record high is 76°, in 2025; the record low −3°, in 1940. The most rain on this date, 0.91 in, fell in 1926.
