Limon’s center stands about 5,360 ft above sea level. Within three miles the land runs from 5,300 ft to 5,500 ft, a difference of 200 ft: rolling country. The highest named summit within 15 miles is Cedar Point, about 5,990 ft, 10 miles northwest.
Under the town center the state geologic map shows Pierre Shale--Upper unit, from the Late Cretaceous, 66 to 100 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 27×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 9 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 8 mi of the line.
Sandstone. Age: Late Cretaceous, 66 to 100 million years old. About 4 mi of the line.
Sand, silt. Age: Quaternary, less than 2.6 million years old. About 3 mi of the line.
Shale, claystone, sandstone. Age: Late Cretaceous, 66 to 100 million years old. About 0.2 mi of the line.

A raindrop that lands in Limon reaches the Gulf of America by way of Lake Creek, Big Sandy Creek, the Arkansas and the Mississippi: about 1,840 river miles.
Lakes on the way: Murray Lake and Ozark Lake.
800 miles of the trip are on the Arkansas.

Limon has a cold semi-arid climate. Summer afternoons average 87° in July; winter nights fall to about 10° in January. About 15 inches of rain fall in a normal year.
On November 14 Limon normally reaches 53° and falls to 18°. The record high is 76°, in 2025; the record low −5°, in 1959. The most rain on this date, 0.54 in, fell in 1993.
