The Colome plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
84° on Nov. 14, 1953, the hottest reading for this week of the year since 1910. Next is 81° in 2025.
Colome’s center stands about 2,300 ft above sea level. Within three miles the land runs from 2,180 ft to 2,340 ft, a difference of 160 ft: gently rolling country.
Under the town center the state geologic map shows Eolian Deposits (silt, sand), from the Quaternary, less than 2.6 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 34×. 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, limestone, siltstone. Age: Miocene to Pliocene, 2.6 to 23 million years old. About 10 mi of the line.
Shale, bentonite. Age: Late Cretaceous, 66 to 100 million years old. About 9 mi of the line.
Silt, sand. Age: Quaternary, less than 2.6 million years old. About 4 mi of the line.
Coarse-detrital, fine-detrital. Age: Quaternary, less than 2.6 million years old. About 1 mi of the line.

A raindrop that lands in Colome reaches the Gulf of America by way of Ponca Creek, the Missouri and the Mississippi: about 2,150 river miles.
Lake on the way: Lewis and Clark Lake.
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 Colome; river miles along the main stem, rounded.
Colome has a hot-summer humid continental climate. Summer afternoons average 89° in July; winter nights fall to about 12° in January. A normal year brings about 49 inches of snow; with the rain, that comes to about 23 inches of water.
On November 14 Colome normally reaches 50° and falls to 26°. The record high is 84°, in 1953; the record low −13°, in 1940. The most rain on this date, 0.24 in, fell in 1997.
