78° on Nov. 11, 2020, the hottest reading for this week of the year since 1893. Next is 74° in 1893.
Iberia’s center stands about 1,100 ft above sea level. Within three miles the land runs from 1,030 ft to 1,230 ft, a difference of 200 ft: rolling country. The highest named summit within 15 miles is Ralston Knob, about 1,420 ft, 13 miles northeast.
Under the town center the state geologic map shows Berea Sandstone and Bedford Shale, Undivided (sandstone, shale), from the Devonian, 359 to 422 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 38×. 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, siltstone, sandstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 9 mi of the line.
Shale, black-shale. Age: Devonian, 359 to 422 million years old. About 8 mi of the line.
Sandstone, shale. Age: Devonian, 359 to 422 million years old. About 3 mi of the line.
Limestone. Age: Devonian, 359 to 422 million years old. About 2 mi of the line.
Black-shale. Age: Carboniferous, 324 to 359 million years old. About 1 mi of the line.
Shale. Age: Devonian, 359 to 422 million years old. About 0.6 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Iberia reaches the Gulf of America by way of Flat Run, the Olentangy, the Scioto, the Ohio and the Mississippi: about 1,790 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 Iberia; river miles along the main stem, rounded.
Iberia has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 20° in January. A normal year brings about 23 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Iberia normally reaches 52° and falls to 35°. The record high is 72°, in 1909; the record low 6°, in 2019. The most rain on this date, 1.15 in, fell in 1972.
Normals 1991–2020 and records since 1893 at Bucyrus, 12 miles northwest, 140 ft lower. NOAA, through RCC-ACIS.
