Carlisle’s center stands about 880 ft above sea level. Within three miles the land runs from 810 ft to 1,020 ft, a difference of 210 ft: 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 48×. 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: Middle Ordovician, 459 to 471 million years old. About 11 mi of the line.
Shale, limestone. Age: Ordovician, 445 to 487 million years old. About 10 mi of the line.
Limestone. Age: Ordovician, 445 to 487 million years old. About 3 mi of the line.

A raindrop that lands in Carlisle reaches the Gulf of America by way of the Brushy Fork, Big Brushy Creek, Hinkston Creek, the South Fork Licking, the Licking, the Ohio and the Mississippi: about 1,620 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 87° in July; winter nights fall to about 23° in January. About 48 inches of rain fall in a normal year.
