75° on Nov. 14, 1999, the hottest reading for this week of the year since 1921. Next is 75° in 2001.
Larrabee’s center stands about 1,380 ft above sea level. Within three miles the land runs from 1,190 ft to 1,450 ft, a difference of 260 ft: rolling country.
Under the town center the state geologic map shows Dakata and Windrow Formations (sandstone, shale), from the Early Cretaceous to Late Cretaceous, 94 to 113 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 53×. 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 to Late Cretaceous, 94 to 113 million years old. About 24 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 Larrabee reaches the Gulf of America by way of Gray Creek, Mill Creek, the Little Sioux, the Missouri and the Mississippi: about 1,940 river miles.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Larrabee; river miles along the main stem, rounded.
Larrabee has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 7° in January. A normal year brings about 38 inches of snow; with the rain, that comes to about 31 inches of water.
On November 14 Larrabee normally reaches 46° and falls to 25°. The record high is 75°, in 1999; the record low −17°, in 1959. The most rain on this date, 1.38 in, fell in 1926.
Normals 1991–2020 and records since 1921 at Cherokee, 7 miles south, 170 ft lower. NOAA, through RCC-ACIS.
