83° on Nov. 14, 1999, the hottest reading for this week of the year since 1893. Next is 81° in 2016.
Chester’s center stands about 1,630 ft above sea level. Within three miles the land runs from 1,560 ft to 1,650 ft, a difference of 90 ft: gently rolling country.
Under the town center the state geologic map shows Dakota Group (sandstone, shale), from the Early Cretaceous, 100 to 145 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.
Sandstone, shale. Age: Early Cretaceous, 100 to 145 million years old. About 14 mi of the line.
Silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 8 mi of the line.
Sand, silt, clay. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.7 mi of the line.

A raindrop that lands in Chester reaches the Gulf of America by way of Rose Creek, the Little Blue, the Big Blue, the Kansas, the Missouri and the Mississippi: about 1,870 river miles.
Lake on the way: Tuttle Creek 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 Chester; river miles along the main stem, rounded.
Chester has a hot-summer humid continental climate. Summer afternoons average 89° in July; winter nights fall to about 14° in January. A normal year brings about 23 inches of snow; with the rain, that comes to about 31 inches of water.
On November 14 Chester normally reaches 53° and falls to 28°. The record high is 83°, in 1999; the record low −4°, in 1940. The most rain on this date, 1.10 in, fell in 1926.
