70° on Nov. 12, 2005, the hottest reading for this week of the year since 1940. Next is 65° in 2001.
Folden’s center stands about 1,510 ft above sea level. Within three miles the land runs from 1,400 ft to 1,640 ft, a difference of 240 ft: rolling country. The highest named summit within 15 miles is Inspiration Peak, about 1,720 ft, 9 miles southwest.
Under the town center the state geologic map shows Schist of sedimentary protolith, from the Neoarchean, 2.5 to 2.8 billion 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 53×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Metabasalt, greenstone. Age: Neoarchean, 2.5 to 2.8 billion years old. About 10 mi of the line.
Schist. Age: Neoarchean, 2.5 to 2.8 billion years old. About 8 mi of the line.
Gabbro, peridotite, pyroxenite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 5 mi of the line.

A raindrop that lands in Folden reaches Hudson Bay by way of West Battle Lake, Otter Tail Lake, the Otter Tail, the Red River of the North and the Nelson: about 1,300 river miles. Past the border it runs north through Canada to Hudson Bay.
Lakes on the way: Otter Tail Lake, West Battle Lake and 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 Folden; river miles along the main stem, rounded.
Folden has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about −2° in January. About 28 inches of rain fall in a normal year.
On November 14 Folden normally reaches 37° and falls to 22°. The record high is 63°, in 1981; the record low 6°, in 1965. The most rain on this date, 0.47 in, fell in 2024.
Normals 1991–2020 and records since 1940 at Ottertail, 13 miles north-northwest, 160 ft lower. NOAA, through RCC-ACIS.
