66° on Nov. 14, 1999, the hottest reading for this week of the year since 1984. Next is 66° in 2025.
Casselton’s center stands about 940 ft above sea level. Within three miles the land runs from 920 ft to 950 ft, a difference of 30 ft: nearly flat ground.
Under the town center the state geologic map shows Belle Fourche-Skull Creek, Undivided (shale, sandstone), from the Early Cretaceous to Late Cretaceous, 66 to 145 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, sandstone. Age: Early Cretaceous to Late Cretaceous, 66 to 145 million years old. About 24 mi of the line.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 0.3 mi of the line.

A raindrop that lands in Casselton reaches Hudson Bay by way of Swan Creek, the Maple, the Sheyenne, the Red River of the North and the Nelson: about 1,120 river miles. Past the border it runs north through Canada to Hudson Bay.
Lake on the way: Lake Winnipeg.
430 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 Casselton; river miles along the main stem, rounded.
Casselton has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about −1° in January. A normal year brings about 37 inches of snow; with the rain, that comes to about 24 inches of water.
On November 14 Casselton normally reaches 38° and falls to 20°. The record high is 66°, in 1999; the record low −2°, in 2014. The most rain on this date, 0.41 in, fell in 1997.
