8° on Nov. 12, 2019, the coldest reading for this week of the year since 1995. Next is 12° in 2014.
Gunn City’s center stands about 870 ft above sea level. Within three miles the land runs from 800 ft to 890 ft, a difference of 90 ft: gently rolling country. The highest named summit within 15 miles is Brookhart Hill, about 1,020 ft, 10 miles west-southwest.
Under the town center the state geologic map shows Marmaton 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.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 8 mi of the line.
Limestone, shale. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Shale, sandstone, siltstone. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.

A raindrop that lands in Gunn City reaches the Gulf of America by way of Camp Branch, Big Creek, the South Grand, the Osage, the Missouri and the Mississippi: about 1,560 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 Gunn City; river miles along the main stem, rounded.
Gunn City 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.
On November 14 Gunn City normally reaches 55° and falls to 35°. The record high is 80°, in 1999; the record low 12°, in 2014. The most rain on this date, 0.45 in, fell in 2020.
Normals 1991–2020 and records since 1995 at Pleasant Hill Wfo, 11 miles north-northwest, 130 ft higher. NOAA, through RCC-ACIS.
