75° on Nov. 16, 1953, the hottest reading for this week of the year since 1914. Next is 72° in 1939.
Wheaton’s center stands about 1,020 ft above sea level. Within three miles the land runs from 990 ft to 1,030 ft, a difference of 40 ft: nearly flat ground.
Under the town center the state geologic map shows Undifferentiated (conglomerate, sandstone, mudstone), from the Late Cretaceous, 72 to 100 million years old.
The section below crosses 5 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.
Felsic-volcanic. Age: Neoarchean, 2.5 to 2.8 billion years old. About 11 mi of the line.
Conglomerate, sandstone, mudstone. Age: Late Cretaceous, 72 to 100 million years old. About 6 mi of the line.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 4 mi of the line.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 3 mi of the line.
Shale, mudstone, marlstone. Age: Late Cretaceous, 66 to 100 million years old. About 0.5 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 Wheaton reaches Hudson Bay by way of the Mustinka, the Bois de Sioux, the Red River of the North and the Nelson: about 1,240 river miles. Past the border it runs north through Canada to Hudson Bay.
Lakes on the way: Lake Traverse and Lake Winnipeg.
550 miles of the trip are on the Red River of the North.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wheaton; river miles along the main stem, rounded.
Wheaton has a hot-summer humid continental climate. Summer afternoons average 82° 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 25 inches of water.
On November 14 Wheaton normally reaches 41° and falls to 24°. The record high is 68°, in 2016; the record low −8°, in 1940. The most rain on this date, 0.55 in, fell in 1951.
