82° on Nov. 14, 1999, the hottest reading for this week of the year since 1893. Next is 76° in 1964.
Clarinda’s center stands about 1,030 ft above sea level. Within three miles the land runs from 970 ft to 1,200 ft, a difference of 230 ft: rolling country.
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.
Shale, mudstone. Age: Late Pennsylvanian, 299 to 307 million years old. About 17 mi of the line.
Limestone, shale. Age: Late Pennsylvanian, 299 to 307 million years old. About 6 mi of the line.
Sandstone, shale. Age: Early Cretaceous to Late Cretaceous, 94 to 113 million years old. About 0.9 mi of the line.

A raindrop that lands in Clarinda reaches the Gulf of America by way of the West Nodaway, the Missouri and the Mississippi: about 1,690 river miles.
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 Clarinda; river miles along the main stem, rounded.
Clarinda has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 12° in January. A normal year brings about 23 inches of snow; with the rain, that comes to about 37 inches of water.
On November 14 Clarinda normally reaches 51° and falls to 28°. The record high is 82°, in 1999; the record low 0°, in 1940. The most rain on this date, 1.35 in, fell in 1972.
