Chippewa Park’s center stands about 1,020 ft above sea level. Within three miles the land runs from 990 ft to 1,040 ft, a difference of 50 ft: nearly flat ground. The highest named summit within 15 miles is Campbell Hill, about 1,550 ft, 13 miles southeast.
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 40×. 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 Chippewa Park reaches the Gulf of America by way of 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 Chippewa Park; river miles along the main stem, rounded.
Chippewa Park has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 18° in January. About 43 inches of rain fall in a normal year.
On November 14 Chippewa Park normally reaches 50° and falls to 32°. The record high is 72°, in 1931; the record low 8°, in 2019. The most rain on this date, 1.77 in, fell in 1993.
Normals 1991–2020 and records since 1894 at Bellefontaine, 13 miles south-southeast, 160 ft higher. NOAA, through RCC-ACIS.
