Otter Creek’s center stands about 1,210 ft above sea level. Within three miles the land runs from 1,000 ft to 1,390 ft, a difference of 390 ft: rolling country. The highest named summit within 15 miles is Wheeler Hill, about 1,410 ft, 2 miles west.
Under the town center the state geologic map shows Shenango Formation (sandstone), from the Carboniferous, 324 to 359 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 31×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone. Age: Carboniferous, 324 to 359 million years old. About 10 mi of the line.
Siltstone, shale. Age: Carboniferous, 324 to 359 million years old. About 8 mi of the line.
Sandstone, conglomerate. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.
Shale. Age: Late Devonian, 359 to 384 million years old. About 1 mi of the line.

A raindrop that lands in Otter Creek reaches the Gulf of America by way of Otter Creek, Neshannock Creek, the Shenango, the Beaver, the Ohio and the Mississippi: about 1,980 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 Otter Creek; river miles along the main stem, rounded.
Otter Creek has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 16° in January. A normal year brings about 62 inches of snow; with the rain, that comes to about 44 inches of water.
On November 14 Otter Creek normally reaches 50° and falls to 32°. The record high is 70°, in 1989; the record low 13°, in 1933. The most rain on this date, 1.22 in, fell in 1972.
Normals 1991–2020 and records since 1931 at Jamestown 2 NW, 12 miles northwest, 180 ft lower. NOAA, through RCC-ACIS.
