4° on Nov. 17, 1959, the coldest reading for this week of the year since 1914. Next is 4° in 2019.
Antioch’s center stands about 880 ft above sea level. Within three miles the land runs from 860 ft to 900 ft, a difference of 40 ft: nearly flat ground.
Under the town center the state geologic map shows Wabash Formation (limestone, dolostone), from the Silurian, 422 to 445 million years old.
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.
Limestone, dolostone. Age: Devonian, 359 to 422 million years old. About 13 mi of the line.
Black-shale. Age: Devonian to Carboniferous, 324 to 422 million years old. About 6 mi of the line.
Limestone, dolostone. Age: Silurian, 422 to 445 million years old. About 5 mi of the line.

A raindrop that lands in Antioch reaches the Gulf of America by way of Prairie Creek, South Fork Wildcat Creek, Wildcat Creek, Big Bayou, the Wabash River Old Channel, the Old Channel Wabash, the Ohio and the Mississippi: about 1,460 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 Antioch; river miles along the main stem, rounded.
Antioch has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 19° in January. A normal year brings about 24 inches of snow; with the rain, that comes to about 43 inches of water.
On November 14 Antioch normally reaches 51° and falls to 34°. The record high is 74°, in 1931; the record low 12°, in 1986. The most rain on this date, 2.55 in, fell in 1993.
Normals 1991–2020 and records since 1914 at Frankfort Disposal, 5 miles north. NOAA, through RCC-ACIS.
