85° on Nov. 15, 1956, the hottest reading for this week of the year since 1878. Next is 78° in 1958.
Harrisville’s center stands about 1,230 ft above sea level. Within three miles the land runs from 870 ft to 1,260 ft, a difference of 390 ft: rolling country.
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 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.
Mudstone, shale, siltstone. Age: Carboniferous to Permian, 252 to 324 million years old. About 9 mi of the line.
Shale, siltstone, mudstone. Age: Carboniferous, 299 to 324 million years old. About 8 mi of the line.
Shale, siltstone, mudstone. Age: Carboniferous, 299 to 324 million years old. About 7 mi of the line.
Fine-detrital, coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Harrisville reaches the Gulf of America by way of Sloan Run, Wheeling Creek, the Ohio and the Mississippi: about 1,870 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 Harrisville; river miles along the main stem, rounded.
Harrisville has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 22° in January. About 38 inches of rain fall in a normal year.
On November 14 Harrisville normally reaches 52° and falls to 36°. The record high is 74°, in 1989; the record low 10°, in 1920. The most rain on this date, 1.10 in, fell in 1997.
