70° on Nov. 12, 2005, the hottest reading for this week of the year since 1893. Next is 68° in 1953.
Clifford’s center stands about 1,050 ft above sea level. Within three miles the land runs from 1,000 ft to 1,120 ft, a difference of 120 ft: gently rolling country.
Under the town center the state geologic map shows Belle Fourche Formation (shale), from the Late Cretaceous, 66 to 100 million years old.
The section below crosses 2 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 14 mi of the line.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 10 mi of the line.

A raindrop that lands in Clifford reaches Hudson Bay by way of the North Branch Elm, the Elm, the Red River of the North and the Nelson: about 1,100 river miles. Past the border it runs north through Canada to Hudson Bay.
Lake on the way: Lake Winnipeg.
400 miles of the trip are on the Nelson.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Clifford; river miles along the main stem, rounded.
Clifford has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about −4° in January. About 24 inches of rain fall in a normal year.
On November 14 Clifford normally reaches 37° and falls to 18°. The record high is 65°, in 1953; the record low −15°, in 1919. The most rain on this date, 0.90 in, fell in 1922.
