82° on Nov. 15, 2025, the hottest reading for this week of the year since 1894. Next is 81° in 1999.
Gibbon’s center stands about 2,070 ft above sea level. Within three miles the land runs from 2,040 ft to 2,090 ft, a difference of 50 ft: nearly flat ground.
Under the town center the state geologic map shows Ogallala Group or Formation (siltstone-mudstone, conglomerate-sandstone), from the Miocene, 5.3 to 23 million years old.
The section below crosses 2 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.
Siltstone-mudstone, conglomerate-sandstone. Age: Miocene, 5.3 to 23 million years old. About 23 mi of the line.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 1 mi of the line.

A raindrop that lands in Gibbon reaches the Gulf of America by way of the Wood, the Platte, the Missouri and the Mississippi: about 1,960 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 Gibbon; river miles along the main stem, rounded.
Gibbon has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 14° in January. A normal year brings about 22 inches of snow; with the rain, that comes to about 26 inches of water.
On November 14 Gibbon normally reaches 51° and falls to 26°. The record high is 81°, in 1999; the record low −5°, in 1959. The most rain on this date, 0.65 in, fell in 1909.
