11° on Nov. 17, 1997, the coldest reading for this week of the year since 1902. Next is 13° in 1916.
Lebanon’s center stands about 530 ft above sea level. Within three miles the land runs from 500 ft to 720 ft, a difference of 220 ft: rolling country. The highest named summit within 15 miles is Mount Defiance, about 1,360 ft, 12 miles southeast.
Under the town center the state geologic map shows Stones River Group; Lebanon Limestone, from the Ordovician, 445 to 487 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 26×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone. Age: Ordovician, 445 to 487 million years old. About 11 mi of the line.
Limestone. Age: Ordovician, 445 to 487 million years old. About 8 mi of the line.
Fine-detrital, coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.
Limestone, calcarenite. Age: Ordovician, 445 to 487 million years old. About 2 mi of the line.
Shale, limestone. Age: Ordovician, 445 to 487 million years old. About 0.5 mi of the line.

A raindrop that lands in Lebanon reaches the Gulf of America by way of Bartons Creek, the Cumberland, the Ohio and the Mississippi: about 1,290 river miles.
Lake on the way: Bards Lake.
970 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 humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 28° in January. About 54 inches of rain fall in a normal year.
On November 14 Lebanon normally reaches 61° and falls to 37°. The record high is 79°, in 1902; the record low 15°, in 2019. The most rain on this date, 3.30 in, fell in 1915.
