Rosholt’s center stands about 1,080 ft above sea level. Within three miles the land runs from 1,020 ft to 1,100 ft, a difference of 80 ft: gently rolling country.
Under the town center the state geologic map shows Carlile 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 13 mi of the line.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 5 mi of the line.
Conglomerate, sandstone, mudstone. Age: Late Cretaceous, 72 to 100 million years old. About 3 mi of the line.
Tonalite, granodiorite, diorite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 2 mi of the line.
Shale, mudstone, marlstone. Age: Late Cretaceous, 66 to 100 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Rosholt reaches Hudson Bay by way of Big Slough, the Bois de Sioux, the Red River of the North and the Nelson: about 1,240 river miles. Past the border it runs north through Canada to Hudson Bay.
Lake on the way: Lake Winnipeg.
550 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 Rosholt; river miles along the main stem, rounded.
Rosholt has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 1° in January. A normal year brings about 49 inches of snow; with the rain, that comes to about 26 inches of water.
On November 14 Rosholt normally reaches 40° and falls to 22°. The record high is 69°, in 2001; the record low −2°, in 2014. The most rain on this date, 0.51 in, fell in 1951.
Normals 1991–2020 and records since 1923 at Victor 4 N, 6 miles northwest. NOAA, through RCC-ACIS.
