70° on Nov. 14, 2025, the hottest reading for this week of the year since 1964. Next is 69° in 1981.
Bergen’s center stands about 1,570 ft above sea level. Within three miles the land runs from 1,560 ft to 1,630 ft, a difference of 70 ft: gently rolling country. The highest named summit within 15 miles is Dogden Butte, about 2,280 ft, 13 miles south.
Under the town center the state geologic map shows Cannonball Formation (shale, sandstone), from the Paleocene, 56 to 66 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 36×. 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: Paleocene, 56 to 66 million years old. About 15 mi of the line.
Claystone, siltstone. Age: Paleocene, 56 to 66 million years old. About 4 mi of the line.
Shale, sandstone. Age: Late Cretaceous, 66 to 100 million years old. About 3 mi of the line.
Sandstone, siltstone, claystone. Age: Late Cretaceous, 66 to 100 million years old. About 2 mi of the line.

A raindrop that lands in Bergen reaches Hudson Bay by way of the Wintering, the Souris, the Assiniboine, the Red River of the North and the Nelson: about 1,150 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.

Bergen has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about −3° in January. About 18 inches of rain fall in a normal year.
On November 14 Bergen normally reaches 36° and falls to 17°. The record high is 70°, in 2025; the record low −6°, in 1996. The most rain on this date, 0.55 in, fell in 1994.
Normals 1991–2020 and records since 1964 at Drake 9 NE, 19 miles east. NOAA, through RCC-ACIS.
