74° on Nov. 11, 2022, the hottest reading for this week of the year since 1966. Next is 73° in 1989.
Creston’s center stands about 900 ft above sea level. Within three miles the land runs from 800 ft to 940 ft, a difference of 140 ft: gently rolling country.
Under the town center the state geologic map shows Ancell Group (sandstone, limestone, dolostone), from the Middle Ordovician to Late Ordovician, 454 to 468 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 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, limestone, dolostone. Age: Middle Ordovician to Late Ordovician, 454 to 468 million years old. About 10 mi of the line.
Dolostone, limestone. Age: Late Ordovician, 447 to 459 million years old. About 10 mi of the line.
Dolostone, limestone. Age: Late Ordovician, 454 to 459 million years old. About 4 mi of the line.

A raindrop that lands in Creston reaches the Gulf of America by way of the Kyte, the Rock River and the Mississippi: about 1,590 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Creston; river miles along the main stem, rounded.
Creston has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 13° in January. A normal year brings about 33 inches of snow; with the rain, that comes to about 37 inches of water.
On November 14 Creston normally reaches 47° and falls to 30°. The record high is 73°, in 1999; the record low 2°, in 1986. The most rain on this date, 0.34 in, fell in 1994.
Normals 1991–2020 and records since 1966 at De Kalb, 10 miles east. NOAA, through RCC-ACIS.
