76° on Nov. 11, 2022, the hottest reading for this week of the year since 1895. Next is 75° in 1911.
Coleta’s center stands about 830 ft above sea level. Within three miles the land runs from 700 ft to 860 ft, a difference of 160 ft: gently rolling country.
Under the town center the state geologic map shows Silurian System undivided (dolostone, limestone), from the Silurian, 422 to 445 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 62×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone, limestone. Age: Silurian, 422 to 445 million years old. About 12 mi of the line.
Dolostone, limestone. Age: Late Ordovician, 447 to 459 million years old. About 9 mi of the line.
Shale, limestone. Age: Late Ordovician, 445 to 454 million years old. About 3 mi of the line.

A raindrop that lands in Coleta reaches the Gulf of America by way of Little Spring Creek, Rock Creek, the Rock River and the Mississippi: about 1,530 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Coleta; river miles along the main stem, rounded.
Coleta has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 12° in January. A normal year brings about 32 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Coleta normally reaches 48° and falls to 29°. The record high is 75°, in 1999; the record low 3°, in 1996. The most rain on this date, 1.25 in, fell in 1926.
Normals 1991–2020 and records since 1895 at Morrison, 11 miles southwest, 200 ft lower. NOAA, through RCC-ACIS.
