67° on Nov. 17, 1953, the hottest reading for this week of the year since 1890. Next is 66° in 2001.
Gentilly’s center stands about 930 ft above sea level. Within three miles the land runs from 870 ft to 1,020 ft, a difference of 150 ft: gently rolling country.
Under the town center the state geologic map shows Tonalite-leucodiorite plutons (tonalite, dioritic), from the Neoarchean, 2.5 to 2.8 billion years old.
The section below crosses 8 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.
Tonalite, dioritic. Age: Neoarchean, 2.5 to 2.8 billion years old. About 7 mi of the line.
Metabasalt, greenstone. Age: Neoarchean, 2.5 to 2.8 billion years old. About 6 mi of the line.
Granitic. Age: Neoarchean, 2.5 to 2.8 billion years old. About 3 mi of the line.
Granodiorite, diorite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 3 mi of the line.
Biotite-schist, migmatite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 2 mi of the line.
Gabbro, peridotite, pyroxenite. 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. 2 smaller units along the line are not listed.

A raindrop that lands in Gentilly reaches Hudson Bay by way of Kripple Creek, the Red Lake, the Red River of the North and the Nelson: about 1,010 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.

Gentilly 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 Gentilly 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, 8 miles west-northwest. NOAA, through RCC-ACIS.
