−23° on Nov. 14, 1959, the coldest reading for this week of the year since 1893. Next is −19° in 1940.
Presho’s center stands about 1,800 ft above sea level. Within three miles the land runs from 1,740 ft to 1,930 ft, a difference of 190 ft: gently rolling country. The highest named summit within 15 miles is Stony Butte, about 2,120 ft, 15 miles northwest.
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 46×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, bentonite. Age: Late Cretaceous, 66 to 100 million years old. About 15 mi of the line.
Silt, sand. Age: Quaternary, less than 2.6 million years old. About 8 mi of the line.
Coarse-detrital, fine-detrital. Age: Quaternary, less than 2.6 million years old. About 0.8 mi of the line.
Coarse-detrital, clay. Age: Quaternary, less than 2.6 million years old. About 0.3 mi of the line.

A raindrop that lands in Presho reaches the Gulf of America by way of Medicine Creek, the Missouri and the Mississippi: about 2,240 river miles.
Lakes on the way: Lake Sharpe, Lake Francis Case and Lewis and Clark Lake.
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 Presho; river miles along the main stem, rounded.
Presho has a hot-summer humid continental climate. Summer afternoons average 90° in July; winter nights fall to about 9° in January. A normal year brings about 40 inches of snow; with the rain, that comes to about 21 inches of water.
On November 14 Presho normally reaches 48° and falls to 23°. The record high is 78°, in 1942; the record low −23°, in 1959. The most rain on this date, 0.50 in, fell in 1927.
Normals 1991–2020 and records since 1893 at Kennebec, 10 miles east, 120 ft lower. NOAA, through RCC-ACIS.
