Fort Loramie’s center stands about 960 ft above sea level. Within three miles the land runs from 940 ft to 1,040 ft, a difference of 100 ft: gently rolling country.
Under the town center the state geologic map shows Cincinnati Group as used by Wickstrom (1990) (shale, dolostone, limestone), from the Ordovician, 445 to 487 million years old.
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 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.
Dolostone. Age: Silurian, 425 to 445 million years old. About 12 mi of the line.
Shale, dolostone, limestone. Age: Ordovician, 445 to 487 million years old. About 9 mi of the line.
Dolostone, limestone, shale. Age: Silurian, 422 to 445 million years old. About 4 mi of the line.

A raindrop that lands in Fort Loramie reaches the Gulf of America by way of Loramie Creek, the Great Miami, the Ohio and the Mississippi: about 1,590 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 Fort Loramie; river miles along the main stem, rounded.
Fort Loramie 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 Fort Loramie 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.
