75° on Nov. 15, 1953, the hottest reading for this week of the year since 1893. Next is 73° in 2001.
Canova’s center stands about 1,530 ft above sea level. Within three miles the land runs from 1,450 ft to 1,580 ft, a difference of 130 ft: gently rolling country.
Under the town center the state geologic map shows Sioux Quartzite, from the Paleoproterozoic, 1.6 to 2.5 billion years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 54×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Chalk, marlstone, shale. Age: Late Cretaceous, 66 to 100 million years old. About 14 mi of the line.
Quartzite. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 5 mi of the line.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 4 mi of the line.
Shale, bentonite. Age: Late Cretaceous, 66 to 100 million years old. About 1 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 Canova reaches the Gulf of America by way of Wolf Creek, the James, the Missouri and the Mississippi: about 2,090 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 Canova; river miles along the main stem, rounded.
Canova has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 5° in January. A normal year brings about 36 inches of snow; with the rain, that comes to about 26 inches of water.
On November 14 Canova normally reaches 48° and falls to 22°. The record high is 71°, in 1953; the record low −18°, in 1940. The most rain on this date, 0.69 in, fell in 1928.
Normals 1991–2020 and records since 1893 at Howard, 9 miles north. NOAA, through RCC-ACIS.
