70° on Nov. 13, 1999, the hottest reading for this week of the year since 1917. Next is 69° in 1953.
Correll’s center stands about 980 ft above sea level. Within three miles the land runs from 930 ft to 1,040 ft, a difference of 110 ft: gently rolling country.
Under the town center the state geologic map shows Granitic intrusion, from the Neoarchean, 2.5 to 2.8 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 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.
Granitic. Age: Neoarchean, 2.5 to 2.8 billion years old. About 12 mi of the line.
Conglomerate, sandstone, mudstone. Age: Late Cretaceous, 72 to 100 million years old. About 6 mi of the line.
Orthogneiss, migmatite. Age: Paleoarchean to Mesoarchean, 2.8 to 3.6 billion years old. About 4 mi of the line.
Orthogneiss. Age: Paleoarchean to Mesoarchean, 2.8 to 3.6 billion years old. About 2 mi of the line.

A raindrop that lands in Correll reaches the Gulf of America by way of the Minnesota and the Mississippi: about 2,130 river miles.
Lake on the way: Lake Pepin.
1,750 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Correll; river miles along the main stem, rounded.
Correll has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 3° in January. A normal year brings about 43 inches of snow; with the rain, that comes to about 26 inches of water.
On November 14 Correll normally reaches 42° and falls to 24°. The record high is 68°, in 2025; the record low −9°, in 1940. The most rain on this date, 0.27 in, fell in 1926.
Normals 1991–2020 and records since 1917 at Artichoke Lake 1 E, 11 miles north, 120 ft higher. NOAA, through RCC-ACIS.
