70° on Nov. 12, 2005, the hottest reading for this week of the year since 1940. Next is 65° in 2001.
Inman’s center stands about 1,440 ft above sea level. Within three miles the land runs from 1,410 ft to 1,510 ft, a difference of 100 ft: gently rolling country. The highest named summit within 15 miles is Black Peak, about 1,670 ft, 5 miles southwest.
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 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 47×. 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 14 mi of the line.
Schist. Age: Neoarchean, 2.5 to 2.8 billion years old. About 7 mi of the line.
Granodiorite, diorite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 3 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 Inman reaches the Gulf of America by way of the Leaf, the Redeye, the Crow Wing and the Mississippi: about 2,060 river miles.
Lake on the way: Lake Pepin.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Inman; river miles along the main stem, rounded.
Inman has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about −2° in January. About 28 inches of rain fall in a normal year.
On November 14 Inman normally reaches 37° and falls to 22°. The record high is 63°, in 1981; the record low 6°, in 1965. The most rain on this date, 0.47 in, fell in 2024.
Normals 1991–2020 and records since 1940 at Ottertail, 12 miles northwest. NOAA, through RCC-ACIS.
