65° on Nov. 15, 2025, the hottest reading for this week of the year since 1943. Next is 64° in 1981.
Greenwood’s center stands about 1,200 ft above sea level. Within three miles the land runs from 1,190 ft to 1,250 ft, a difference of 60 ft: gently rolling country.
Under the town center the state geologic map shows Granitic intrusion, from the Neoarchean, 2.5 to 2.8 billion 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 48×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granitic. Age: Neoarchean, 2.5 to 2.8 billion years old. About 12 mi of the line.
Metabasalt, greenstone. Age: Neoarchean, 2.5 to 2.8 billion years old. About 8 mi of the line.
Conglomerate, sandstone, mudstone. Age: Late Cretaceous, 72 to 100 million years old. About 2 mi of the line.
Biotite-schist, migmatite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 1 mi of the line.

A raindrop that lands in Greenwood reaches Hudson Bay by way of the Clearwater, the Red Lake, the Red River of the North and the Nelson: about 1,110 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 Greenwood; river miles along the main stem, rounded.
Greenwood has a warm-summer humid continental climate. Summer afternoons average 77° in July; winter nights fall to about −3° in January. About 23 inches of rain fall in a normal year.
On November 14 Greenwood normally reaches 35° and falls to 21°. The record high is 64°, in 2016; the record low −11°, in 1959. The most rain on this date, 0.81 in, fell in 1944.
Normals 1991–2020 and records since 1943 at Red Lake Indian Agcy, 19 miles east-northeast. NOAA, through RCC-ACIS.
