Carlisle’s center stands about 690 ft above sea level. Within three miles the land runs from 660 ft to 920 ft, a difference of 260 ft: rolling country. The highest named summit within 15 miles is Miamisburg Mound, about 930 ft, 4 miles north-northeast.
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 44×. 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, limestone. Age: Late Ordovician, 445 to 454 million years old. About 6 mi of the line.
Shale, limestone. Age: Late Ordovician, 445 to 459 million years old. About 4 mi of the line.
Shale, limestone. Age: Late Ordovician, 445 to 454 million years old. About 2 mi of the line.
Limestone. Age: Silurian, 422 to 445 million years old. About 0.3 mi of the line.

A raindrop that lands in Carlisle reaches the Gulf of America by way of Dry Run, the Great Miami, the Ohio and the Mississippi: about 1,520 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 Carlisle; river miles along the main stem, rounded.
Carlisle has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 20° in January. About 42 inches of rain fall in a normal year.
On November 14 Carlisle normally reaches 54° and falls to 32°. The record high is 72°, in 2011; the record low 10°, in 1986. The most rain on this date, 1.53 in, fell in 1972.
