68° on Nov. 16, 2016, the hottest reading for this week of the year since 1906. Next is 67° in 1953.
Tenstrike’s center stands about 1,410 ft above sea level. Within three miles the land runs from 1,330 ft to 1,460 ft, a difference of 130 ft: gently rolling country.
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 4 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 11 mi of the line.
Granitic. Age: Neoarchean, 2.5 to 2.8 billion years old. About 9 mi of the line.
Granite, granodiorite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 4 mi of the line.
Felsic-volcanic. Age: Neoarchean, 2.5 to 2.8 billion years old. About 1 mi of the line.

A raindrop that lands in Tenstrike reaches the Gulf of America by way of Buck Lake and the Mississippi: about 2,260 river miles.
Lakes on the way: Sugar Lake, Buck Lake and Lake Pepin.
1,750 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Tenstrike; river miles along the main stem, rounded.
Tenstrike has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about −4° 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 Tenstrike normally reaches 37° and falls to 20°. The record high is 66°, in 2016; the record low −13°, in 1959. The most rain on this date, 1.05 in, fell in 1951.
Normals 1991–2020 and records since 1906 at Cass Lake, 19 miles south, 110 ft lower. NOAA, through RCC-ACIS.
