74° on Nov. 15, 1999, the hottest reading for this week of the year since 1897. Next is 68° in 1939.
Berthold’s center stands about 2,090 ft above sea level. Within three miles the land runs from 1,980 ft to 2,240 ft, a difference of 260 ft: rolling country.
Under the town center the state geologic map shows Sentinel Butte Formation (siltstone, claystone, sandstone), from the Paleocene, 56 to 66 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 28×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Siltstone, claystone, sandstone. Age: Paleocene, 56 to 66 million years old. About 13 mi of the line.
Claystone, siltstone. Age: Paleocene, 56 to 66 million years old. About 9 mi of the line.
Shale, sandstone. Age: Paleocene, 56 to 66 million years old. About 3 mi of the line.

A raindrop that lands in Berthold reaches Hudson Bay by way of the Des Lacs, the Souris, the Assiniboine, 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.
400 miles of the trip are on the Nelson.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Berthold; river miles along the main stem, rounded.
Berthold has a warm-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 2° in January. About 18 inches of rain fall in a normal year.
On November 14 Berthold normally reaches 39° and falls to 20°. The record high is 68°, in 1939; the record low −19°, in 1940. The most rain on this date, 1.20 in, fell in 1944.
