75° on Nov. 12, 1999, the hottest reading for this week of the year since 1932. Next is 71° in 2025.
Inverness’s center stands about 3,300 ft above sea level. Within three miles the land runs from 3,200 ft to 3,370 ft, a difference of 170 ft: gently rolling country.
Under the town center the state geologic map shows Judith River Formation (sandstone, shale), from the Late Cretaceous, 72 to 84 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 39×. 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: Late Cretaceous, 72 to 84 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 Inverness reaches the Gulf of America by way of the Marias, the Missouri and the Mississippi: about 3,300 river miles.
Lakes on the way: Lake Oahe, Lake Sakakawea, Lake Fort Peck and Lake Sharpe.
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 Inverness; river miles along the main stem, rounded.
Inverness has a cold semi-arid climate. Summer afternoons average 83° in July; winter nights fall to about 8° in January. A normal year brings about 35 inches of snow; with the rain, that comes to about 11 inches of water.
On November 14 Inverness normally reaches 41° and falls to 19°. The record high is 68°, in 1999; the record low −18°, in 2014. The most rain on this date, 0.34 in, fell in 1958.
Normals 1991–2020 and records since 1932 at Joplin, 4 miles west. NOAA, through RCC-ACIS.
