67° on Nov. 17, 1953, the hottest reading for this week of the year since 1890. Next is 66° in 2001.
Tynsid’s center stands about 850 ft above sea level. Within three miles the land runs from 820 ft to 860 ft, a difference of 40 ft: nearly flat ground.
Under the town center the state geologic map shows Granite to granodiorite (granite, granodiorite), from the Neoarchean, 2.5 to 2.8 billion years old.
The section below crosses 7 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.
Granite, granodiorite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 6 mi of the line.
Sandstone, shale. Age: Early Cretaceous, 100 to 145 million years old. About 5 mi of the line.
Age: Precambrian. About 5 mi of the line.
Metabasalt, greenstone. Age: Neoarchean, 2.5 to 2.8 billion years old. About 4 mi of the line.
Granitic. Age: Neoarchean, 2.5 to 2.8 billion years old. About 2 mi of the line.
Felsic-volcanic. Age: Neoarchean, 2.5 to 2.8 billion years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Tynsid reaches Hudson Bay by way of the Red Lake, 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 Tynsid; river miles along the main stem, rounded.
Tynsid has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about −4° in January. About 22 inches of rain fall in a normal year.
On November 14 Tynsid normally reaches 37° and falls to 20°. The record high is 64°, in 2016; the record low −11°, in 1919. The most rain on this date, 0.89 in, fell in 1944.
Normals 1991–2020 and records since 1890 at Crookston Nw Experiment Sta, 15 miles east-northeast. NOAA, through RCC-ACIS.
