Kingman’s center stands about 1,530 ft above sea level. Within three miles the land runs from 1,490 ft to 1,630 ft, a difference of 140 ft: gently rolling country.
Under the town center the state geologic map shows Nippewalla Group (siltstone, sandstone, shale), from the Permian, 252 to 299 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 61×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand, silt, clay. Age: Pleistocene, less than 2.6 million years old. About 12 mi of the line.
Sand, silt, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 6 mi of the line.
Siltstone, sandstone, shale. Age: Permian, 252 to 299 million years old. About 4 mi of the line.
Shale. Age: Permian, 252 to 299 million years old. About 2 mi of the line.

A raindrop that lands in Kingman reaches the Gulf of America by way of the South Fork Ninnescah, the Ninnescah, the Arkansas and the Mississippi: about 1,380 river miles.
Lakes on the way: Murray Lake and Ozark Lake.
600 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Kingman; river miles along the main stem, rounded.
Kingman has a hot-summer humid continental climate. Summer afternoons average 93° in July; winter nights fall to about 19° in January. A normal year brings about 9 inches of snow; with the rain, that comes to about 33 inches of water.
On November 14 Kingman normally reaches 58° and falls to 32°. The record high is 75°, in 1988; the record low 8°, in 2018. The most rain on this date, 0.47 in, fell in 1993.
