80° on Nov. 11, 2020, the hottest reading for this week of the year since 1948. Next is 77° in 2010.
Henryville’s center stands about 510 ft above sea level. Within three miles the land runs from 470 ft to 690 ft, a difference of 220 ft: rolling country. The highest named summit within 15 miles is Silver Hills, about 1,030 ft, 3 miles west-northwest.
Under the town center the state geologic map shows New Albany Shale (black-shale), from the Devonian to Carboniferous, 324 to 422 million years old.
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 31×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Siltstone. Age: Carboniferous, 324 to 359 million years old. About 12 mi of the line.
Black-shale. Age: Devonian to Carboniferous, 324 to 422 million years old. About 8 mi of the line.
Limestone. Age: Silurian, 422 to 445 million years old. About 2 mi of the line.
Limestone, dolostone. Age: Devonian, 359 to 422 million years old. About 1 mi of the line.
Limestone, shale. Age: Ordovician, 445 to 487 million years old. About 0.3 mi of the line.

A raindrop that lands in Henryville reaches the Gulf of America by way of Silver Creek, the Ohio and the Mississippi: about 1,370 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 Henryville; river miles along the main stem, rounded.
Henryville has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 26° in January. About 48 inches of rain fall in a normal year, with about 4 inches of snow.
Normals 1991–2020 and records since 1948 at Louisville Mcalpine, 18 miles south. NOAA, through RCC-ACIS.
