Canal Winchester’s center stands about 770 ft above sea level. Within three miles the land runs from 730 ft to 960 ft, a difference of 230 ft: rolling country. The highest named summit within 15 miles is Allen Knob, about 1,190 ft, 13 miles southeast.
Under the town center the state geologic map shows Ohio Shale (shale, black-shale), 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 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.
Shale, black-shale. Age: Devonian, 359 to 422 million years old. About 13 mi of the line.
Sandstone, conglomerate. Age: Carboniferous, 324 to 359 million years old. About 7 mi of the line.
Shale, siltstone, sandstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 3 mi of the line.
Shale, sandstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 0.9 mi of the line.

A raindrop that lands in Canal Winchester reaches the Gulf of America by way of Walnut Creek, the Scioto, the Ohio and the Mississippi: about 1,720 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 Canal Winchester; river miles along the main stem, rounded.
Canal Winchester has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 22° in January. A normal year brings about 28 inches of snow; with the rain, that comes to about 42 inches of water.
On November 14 Canal Winchester normally reaches 53° and falls to 35°. The record high is 74°, in 1909; the record low 12°, in 1986. The most rain on this date, 1.26 in, fell in 1897.
