81° on Nov. 12, 1989, the hottest reading for this week of the year since 1962. Next is 81° in 2016.
Clever’s center stands about 1,390 ft above sea level. Within three miles the land runs from 1,190 ft to 1,390 ft, a difference of 200 ft: gently rolling country.
Under the town center the state geologic map shows Channel Sandstones, from the Carboniferous, 299 to 324 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 49×. 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. Age: Carboniferous, 324 to 359 million years old. About 20 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 3 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 1 mi of the line.

A raindrop that lands in Clever reaches the Gulf of America by way of Luce Creek, Terrell Creek, the James, the White River and the Mississippi: about 1,230 river miles.
Lake on the way: Table Rock Lake.
620 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Clever; river miles along the main stem, rounded.
Clever has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 22° in January. A normal year brings about 12 inches of snow; with the rain, that comes to about 46 inches of water.
On November 14 Clever normally reaches 58° and falls to 34°. The record high is 80°, in 1999; the record low 11°, in 2018. The most rain on this date, 1.90 in, fell in 1993.
Normals 1991–2020 and records since 1962 at Billings 1 SW, 6 miles west-northwest. NOAA, through RCC-ACIS.
