65° on Nov. 13, 1999, the hottest reading for this week of the year since 1962. Next is 65° in 2001.
Grandin’s center stands about 900 ft above sea level. Within three miles the land runs from 880 ft to 920 ft, a difference of 40 ft: nearly flat ground.
Under the town center the state geologic map shows Inyan Kara (sandstone, shale), from the Early Cretaceous, 100 to 145 million 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.
Sandstone, shale. Age: Early Cretaceous, 100 to 145 million years old. About 16 mi of the line.
Granitic. Age: Neoarchean, 2.5 to 2.8 billion years old. About 4 mi of the line.
Age: Precambrian. About 4 mi of the line.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 0.9 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Grandin reaches Hudson Bay by way of the Elm, the Red River of the North and the Nelson: about 1,050 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 Grandin; river miles along the main stem, rounded.
Grandin has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about −1° in January. A normal year brings about 41 inches of snow; with the rain, that comes to about 25 inches of water.
On November 14 Grandin normally reaches 38° and falls to 22°. The record high is 62°, in 2025; the record low 0°, in 2014. The most rain on this date, 0.30 in, fell in 1971.
Normals 1991–2020 and records since 1962 at Georgetown 1 E, 15 miles southeast. NOAA, through RCC-ACIS.
