68° on Nov. 17, 1953, the hottest reading for this week of the year since 1895. Next is 66° in 2001.
Littlefork’s center stands about 1,120 ft above sea level. Within three miles the land runs from 1,090 ft to 1,230 ft, a difference of 140 ft: gently rolling country.
Under the town center the state geologic map shows Biotite schist of graywacke protolith, and schist-rich migmatite (biotite-schist, migmatite), from the Neoarchean, 2.5 to 2.8 billion 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.
Biotite-schist, migmatite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 20 mi of the line.
Migmatite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 4 mi of the line.

A raindrop that lands in Littlefork reaches Hudson Bay by way of the Little Fork, the Rainy, the Winnipeg and the Nelson: about 930 river miles. Past the border it runs north through Canada to Hudson Bay.
Lakes on the way: Lake of the Woods and 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 Littlefork; river miles along the main stem, rounded.
Littlefork has a warm-summer humid continental climate. Summer afternoons average 78° in July; winter nights fall to about −6° in January. A normal year brings about 73 inches of snow; with the rain, that comes to about 25 inches of water.
On November 14 Littlefork normally reaches 35° and falls to 19°. The record high is 59°, in 2025; the record low −14°, in 1959. The most rain on this date, 0.60 in, fell in 1909.
Normals 1991–2020 and records since 1895 from the International Falls Area threaded record (International Falls International Airport, 13 miles north-northeast). NOAA, through RCC-ACIS.
