Harrisonville’s center stands about 930 ft above sea level. Within three miles the land runs from 840 ft to 1,030 ft, a difference of 190 ft: gently rolling country. The highest named summit within 15 miles is Miller Hill, about 1,130 ft, 10 miles north-northwest.
Under the town center the state geologic map shows Pleasanton Group (shale, sandstone), from the Carboniferous, 299 to 324 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.
Limestone, shale. Age: Carboniferous, 299 to 324 million years old. About 10 mi of the line.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 7 mi of the line.

A raindrop that lands in Harrisonville reaches the Gulf of America by way of Muddy Creek, the East Branch South Grand, the Old Channel South Grand, the South Grand, the Osage, the Missouri and the Mississippi: about 1,580 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 Harrisonville; river miles along the main stem, rounded.
Harrisonville has a hot-summer humid continental climate. Summer afternoons average 88° in July; winter nights fall to about 21° in January. A normal year brings about 17 inches of snow; with the rain, that comes to about 43 inches of water.
