The Shawnee Hills plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
77° on Nov. 11, 2020, the hottest reading for this week of the year since 1917. Next is 75° in 1949.
Shawnee Hills’s center stands about 900 ft above sea level. Within three miles the land runs from 820 ft to 1,010 ft, a difference of 190 ft: gently rolling country.
Under the town center the state geologic map shows Columbus Limestone, from the Devonian, 359 to 422 million years old.
The section below crosses 4 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. Age: Devonian, 359 to 422 million years old. About 9 mi of the line.
Shale, black-shale. Age: Devonian, 359 to 422 million years old. About 7 mi of the line.
Dolostone. Age: Silurian, 422 to 445 million years old. About 5 mi of the line.
Limestone. Age: Devonian, 359 to 422 million years old. About 3 mi of the line.

A raindrop that lands in Shawnee Hills reaches the Gulf of America by way of the Scioto, the Ohio and the Mississippi: about 1,740 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 Shawnee Hills; river miles along the main stem, rounded.
Shawnee Hills has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 21° in January. A normal year brings about 24 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Shawnee Hills normally reaches 52° and falls to 34°. The record high is 73°, in 1971; the record low 12°, in 1920. The most rain on this date, 1.32 in, fell in 1972.
