3.41 inches of rain fell in two days, the most for this week of the year since records began in 1893. The next wettest, 3.02 inches, fell in 1985.
Pesotum’s center stands about 710 ft above sea level. Within three miles the land runs from 670 ft to 720 ft, a difference of 50 ft: nearly flat ground.
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 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. Age: Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 million years old. About 8 mi of the line.
Limestone. Age: Middle Devonian, 384 to 394 million years old. About 7 mi of the line.
Siltstone. Age: Early Mississippian to Middle Mississippian, 331 to 359 million years old. About 5 mi of the line.
Shale. Age: Middle Devonian to Late Devonian, 359 to 388 million years old. About 4 mi of the line.
Shale, sandstone, coal. Age: Middle Pennsylvanian to Late Pennsylvanian, 304 to 315 million years old. About 0.4 mi of the line.

A raindrop that lands in Pesotum reaches the Gulf of America by way of Hackett Branch, the Scattering Fork, the Embarras, Big Bayou, the Wabash River Old Channel, the Old Channel Wabash, the Ohio and the Mississippi: about 1,380 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Pesotum; river miles along the main stem, rounded.
Pesotum has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 18° in January. A normal year brings about 17 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Pesotum normally reaches 52° and falls to 33°. The record high is 77°, in 1971; the record low 9°, in 2019. The most rain on this date, 2.20 in, fell in 1993.
Normals 1991–2020 and records since 1893 at Tuscola, 8 miles south. NOAA, through RCC-ACIS.
