63° on Nov. 16, 2001, the hottest reading for this week of the year since 1957. Next is 62° in 2025.
Spruce Valley’s center stands about 1,150 ft above sea level. Within three miles the land runs from 1,120 ft to 1,170 ft, a difference of 50 ft: nearly flat ground.
Under the town center the state geologic map shows Mafic metavolcanic rocks (metabasalt, greenstone), from the Neoarchean, 2.5 to 2.8 billion 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.
Metabasalt, greenstone. Age: Neoarchean, 2.5 to 2.8 billion years old. About 9 mi of the line.
Felsic-volcanic. Age: Neoarchean, 2.5 to 2.8 billion years old. About 9 mi of the line.
Granitic. Age: Neoarchean, 2.5 to 2.8 billion years old. About 5 mi of the line.
Plutonic. Age: Archean. About 1 mi of the line.
Granodiorite, diorite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 0.6 mi of the line.

A raindrop that lands in Spruce Valley reaches Hudson Bay by way of the Middle River, the Snake, the Red River of the North and the Nelson: about 960 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 Spruce Valley; river miles along the main stem, rounded.
Spruce Valley has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about −3° in January. About 24 inches of rain fall in a normal year.
On November 14 Spruce Valley normally reaches 36° and falls to 20°. The record high is 62°, in 2025; the record low −4°, in 1959. The most rain on this date, 0.35 in, fell in 1994.
Normals 1991–2020 and records since 1957 at Agassiz Refuge, 12 miles southeast. NOAA, through RCC-ACIS.
