82° on Nov. 11, 2020, the hottest reading for this week of the year since 1893. Next is 80° in 1902.
Massieville’s center stands about 640 ft above sea level. Within three miles the land runs from 590 ft to 1,100 ft, a difference of 510 ft: hilly country. The highest named summit within 15 miles is Potts Hill, about 1,340 ft, 14 miles west-southwest.
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 28×. 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, sandstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 17 mi of the line.
Shale, sandstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 4 mi of the line.
Shale, black-shale. Age: Devonian, 359 to 422 million years old. About 3 mi of the line.

A raindrop that lands in Massieville reaches the Gulf of America by way of Indian Creek, the Scioto, the Ohio and the Mississippi: about 1,650 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 Massieville; river miles along the main stem, rounded.
Massieville has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 22° in January. A normal year brings about 12 inches of snow; with the rain, that comes to about 44 inches of water.
On November 14 Massieville normally reaches 55° and falls to 32°. The record high is 80°, in 1909; the record low 8°, in 1986. The most rain on this date, 1.31 in, fell in 2024.
