75° on Nov. 13, 1999, the hottest reading for this week of the year since 1893. Next is 73° in 1953.
Protivin’s center stands about 1,150 ft above sea level. Within three miles the land runs from 1,120 ft to 1,230 ft, a difference of 110 ft: gently rolling country.
The section below crosses 3 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.
Dolostone, limestone. Age: Middle Devonian, 384 to 394 million years old. About 10 mi of the line.
Limestone, dolostone. Age: Middle Devonian to Late Devonian, 374 to 388 million years old. About 9 mi of the line.
Shale, dolostone. Age: Late Ordovician, 447 to 454 million years old. About 5 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Protivin reaches the Gulf of America by way of Bohemian Creek, the Turkey and the Mississippi: about 1,710 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Protivin; river miles along the main stem, rounded.
Protivin has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 10° in January. A normal year brings about 38 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Protivin normally reaches 47° and falls to 29°. The record high is 71°, in 2025; the record low −7°, in 1916. The most rain on this date, 1.08 in, fell in 1902.
Normals 1991–2020 and records since 1893 at Decorah, 16 miles east-northeast, 290 ft lower. NOAA, through RCC-ACIS.
