5.08 inches of rain fell in two days, the most for this week of the year since records began in 1889. The next wettest, 2.96 inches, fell in 1992.
Hartsburg’s center stands about 630 ft above sea level. Within three miles the land runs from 530 ft to 860 ft, a difference of 330 ft: rolling country.
Under the town center the state geologic map shows Smithville Dolomite, Powell Dolomite, Cotter Dolomite, Jefferson City Dolomite (dolostone), from the Early Ordovician, 471 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 50×. 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: Early Ordovician, 471 to 487 million years old. About 10 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 8 mi of the line.
Clay, silt, sand. Age: Holocene, less than 12,000 years old. About 3 mi of the line.
Limestone, sandstone. Age: Early Devonian to Late Devonian, 359 to 422 million years old. About 2 mi of the line.
Limestone, siltstone. Age: Carboniferous, 324 to 359 million years old. About 2 mi of the line.

A raindrop that lands in Hartsburg reaches the Gulf of America by way of Hart Creek, the Missouri and the Mississippi: about 1,320 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hartsburg; river miles along the main stem, rounded.
Hartsburg has a hot-summer humid continental climate. Summer afternoons average 89° in July; winter nights fall to about 22° in January. A normal year brings about 16 inches of snow; with the rain, that comes to about 41 inches of water.
On November 14 Hartsburg normally reaches 55° and falls to 36°. The record high is 79°, in 2025; the record low 10°, in 1940. The most rain on this date, 1.68 in, fell in 1913.
