73° on Nov. 17, 1953, the hottest reading for this week of the year since 1912. Next is 69° in 1981.
Wyndmere’s center stands about 1,060 ft above sea level. Within three miles the land runs from 1,040 ft to 1,070 ft, a difference of 30 ft: nearly flat ground.
Under the town center the state geologic map shows Greenhorn Formation (shale), from the Late Cretaceous, 66 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.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 9 mi of the line.
Shale, sandstone. Age: Early Cretaceous to Late Cretaceous, 66 to 145 million years old. About 8 mi of the line.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 3 mi of the line.
Age: Precambrian. About 3 mi of the line.
Sandstone, shale. Age: Early Cretaceous, 100 to 145 million years old. About 0.4 mi of the line.

A raindrop that lands in Wyndmere reaches Hudson Bay by way of the Wild Rice, the Red River of the North and the Nelson: about 1,260 river miles. Past the border it runs north through Canada to Hudson Bay.
Lake on the way: Lake Winnipeg.
470 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 Wyndmere; river miles along the main stem, rounded.
Wyndmere has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about −1° in January. About 24 inches of rain fall in a normal year.
On November 14 Wyndmere normally reaches 40° and falls to 21°. The record high is 67°, in 2016; the record low −12°, in 1940. The most rain on this date, 0.57 in, fell in 1951.
