84° on Nov. 13, 1999, the hottest reading for this week of the year since 1893. Next is 81° in 1931.
Hooper’s center stands about 1,230 ft above sea level. Within three miles the land runs from 1,210 ft to 1,320 ft, a difference of 110 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.
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 24 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Hooper reaches the Gulf of America by way of the Elkhorn, the Platte, the Missouri and the Mississippi: about 1,850 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 Hooper; river miles along the main stem, rounded.
Hooper has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 13° in January. About 30 inches of rain fall in a normal year.
On November 14 Hooper normally reaches 50° and falls to 28°. The record high is 74°, in 1990; the record low −4°, in 1940. The most rain on this date, 1.33 in, fell in 1972.
