Jefferson City’s center stands about 1,190 ft above sea level. Within three miles the land runs from 1,040 ft to 1,500 ft, a difference of 460 ft: hilly country. The highest named summit within 15 miles is Donehew Head, about 2,180 ft, 13 miles west-northwest.
Under the town center the state geologic map shows Jonesboro Limestone, Newala Formation, Mascot Dolomite, Kingsport Formation, Longview Dolomite, and Chepultepec Dolomite (limestone, dolostone), from the Ordovician, 445 to 487 million years old.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 15×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone. Age: Cambrian, 487 to 542 million years old. About 11 mi of the line.
Limestone, dolostone. Age: Ordovician, 445 to 487 million years old. About 5 mi of the line.
Shale. Age: Ordovician, 445 to 487 million years old. About 3 mi of the line.
Sandstone. Age: Silurian, 422 to 445 million years old. About 1 mi of the line.
Limestone, dolostone. Age: Cambrian, 487 to 542 million years old. About 1 mi of the line.
Limestone, shale. Age: Cambrian, 487 to 542 million years old. About 0.9 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 3 smaller units along the line are not listed.

A raindrop that lands in Jefferson City reaches the Gulf of America by way of Mossy Creek, the Holston, the Tennessee, the Ohio and the Mississippi: about 1,720 river miles.
Lakes on the way: Guntersville Lake, White Lake (historical), Pickwick Lake and Cummings 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 Jefferson City; river miles along the main stem, rounded.
Jefferson City has a humid subtropical climate. Summer afternoons average 86° in July; winter nights fall to about 29° in January. A normal year brings about 10 inches of snow; with the rain, that comes to about 47 inches of water.
On November 14 Jefferson City normally reaches 58° and falls to 39°. The record high is 73°, in 1999; the record low 23°, in 2014. The most rain on this date, 0.36 in, fell in 1997.
Normals 1991–2020 and records since 1995 at Morristown Wfo, 6 miles east-northeast, 130 ft higher. NOAA, through RCC-ACIS.
