Gilman City’s center stands about 980 ft above sea level. Within three miles the land runs from 850 ft to 990 ft, a difference of 140 ft: gently rolling country.
Under the town center the state geologic map shows Kansas City Group (limestone, shale), from the Carboniferous, 299 to 324 million years old.
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.
Limestone, shale. Age: Carboniferous, 299 to 324 million years old. About 11 mi of the line.

A raindrop that lands in Gilman City reaches the Gulf of America by way of Big Muddy Creek, the Grand River, the Missouri and the Mississippi: about 1,520 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 Gilman City; river miles along the main stem, rounded.
