82° on Nov. 13, 1999, the hottest reading for this week of the year since 1894. Next is 81° in 1941.
Lebanon’s center stands about 2,410 ft above sea level. Within three miles the land runs from 2,360 ft to 2,560 ft, a difference of 200 ft: gently rolling country.
Under the town center the state geologic map shows Niobrara Formation (limestone, shale), from the Late Cretaceous, 66 to 100 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 46×. 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 17 mi of the line.
Limestone, shale. Age: Late Cretaceous, 66 to 100 million years old. About 4 mi of the line.
Sand, silt, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 2 mi of the line.
Silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 1 mi of the line.

A raindrop that lands in Lebanon reaches the Gulf of America by way of Beaver Creek, Sappa Creek, the Republican, the Kansas, the Missouri and the Mississippi: about 2,040 river miles.
Lake on the way: Harlan County 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 Lebanon; river miles along the main stem, rounded.
Lebanon has a dry-winter hot-summer continental climate. Summer afternoons average 91° in July; winter nights fall to about 16° in January. About 20 inches of rain fall in a normal year.
On November 14 Lebanon normally reaches 54° and falls to 26°. The record high is 81°, in 2025; the record low −14°, in 1940. The most rain on this date, 0.62 in, fell in 1926.
