3.85 inches of rain fell in two days, the most for this week of the year since records began in 1890. The next wettest, 3.40 inches, fell in 1985.
Sheldon’s center stands about 920 ft above sea level. Within three miles the land runs from 860 ft to 950 ft, a difference of 90 ft: gently rolling country.
Under the town center the state geologic map shows Cherokee Group - Cabaniss Subgroup, Krebs Subgroup (shale, sandstone, siltstone), from the Carboniferous, 299 to 324 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. 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, sandstone, siltstone. Age: Carboniferous, 299 to 324 million years old. About 14 mi of the line.
Shale, siltstone, mudstone. Age: Carboniferous, 299 to 324 million years old. About 10 mi of the line.

A raindrop that lands in Sheldon reaches the Gulf of America by way of Pleasant Run Creek, Little Dry Wood Creek, the Marmaton, the Little Osage, the Osage, the Missouri and the Mississippi: about 1,620 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 Sheldon; river miles along the main stem, rounded.
Sheldon has a hot-summer humid continental climate. Summer afternoons average 88° in July; winter nights fall to about 22° in January. A normal year brings about 7 inches of snow; with the rain, that comes to about 49 inches of water.
On November 14 Sheldon normally reaches 57° and falls to 35°. The record high is 82°, in 1999; the record low 6°, in 1986. The most rain on this date, 2.25 in, fell in 1926.
