82° on Nov. 11, 2020, the hottest reading for this week of the year since 1893. Next is 80° in 1902.
Franklin Furnace’s center stands about 560 ft above sea level. Within three miles the land runs from 500 ft to 910 ft, a difference of 410 ft: hilly country. The highest named summit within 15 miles is Peach Orchard Hill, about 1,110 ft, 14 miles west-northwest.
Under the town center the state geologic map shows Maxville Limestone; Rushville, Logan, and Cuyhoga Formations, Undivided (shale, siltstone, sandstone), from the Devonian to Carboniferous, 324 to 422 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 32×. 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, siltstone. Age: Carboniferous, 299 to 324 million years old. About 12 mi of the line.
Shale, siltstone. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.
Shale. Age: Devonian to Carboniferous, 324 to 422 million years old. About 5 mi of the line.
Sand, silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 2 mi of the line.
Shale, siltstone, sandstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 0.8 mi of the line.

A raindrop that lands in Franklin Furnace reaches the Gulf of America by way of the Ohio and the Mississippi: about 1,600 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 Franklin Furnace; river miles along the main stem, rounded.
Franklin Furnace has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 23° in January. About 43 inches of rain fall in a normal year.
On November 14 Franklin Furnace normally reaches 57° and falls to 34°. The record high is 79°, in 1955; the record low 10°, in 1986. The most rain on this date, 1.36 in, fell in 2024.
Normals 1991–2020 and records since 1893 at Portsmouth-Sciotoville, 8 miles north-northwest. NOAA, through RCC-ACIS.
