The Humansville plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
83° on Nov. 14, 1999, the hottest reading for this week of the year since 1970. Next is 81° in 2025.
Humansville’s center stands about 960 ft above sea level. Within three miles the land runs from 860 ft to 1,110 ft, a difference of 250 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 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 43×. 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 8 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 8 mi of the line.
Limestone, siltstone. Age: Carboniferous, 324 to 359 million years old. About 4 mi of the line.
Shale, siltstone, mudstone. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.

A raindrop that lands in Humansville reaches the Gulf of America by way of Brush Creek, the Sac, the Osage, the Missouri and the Mississippi: about 1,560 river miles.
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 Humansville; river miles along the main stem, rounded.
Humansville has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 23° in January. A normal year brings about 7 inches of snow; with the rain, that comes to about 45 inches of water.
On November 14 Humansville normally reaches 58° and falls to 38°. The record high is 83°, in 1999; the record low 7°, in 2018. The most rain on this date, 2.16 in, fell in 1985.
