Jackson Center’s center stands about 1,030 ft above sea level. Within three miles the land runs from 1,000 ft to 1,060 ft, a difference of 60 ft: gently rolling country.
Under the town center the state geologic map shows Tymochtee and Greenfield Formations, Undivided (dolostone), from the Silurian, 428 to 445 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 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.

A raindrop that lands in Jackson Center reaches the Gulf of America by way of Jackson Center Creek, Little Muchinippi Creek, Muchinippi Creek, the Great Miami, 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 Jackson Center; river miles along the main stem, rounded.
Jackson Center has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 18° in January. About 42 inches of rain fall in a normal year.
On November 14 Jackson Center normally reaches 52° and falls to 32°. The record high is 71°, in 1989; the record low 2°, in 2019. The most rain on this date, 1.93 in, fell in 1972.
