Smithfield’s center stands about 1,100 ft above sea level. Within three miles the land runs from 960 ft to 1,340 ft, a difference of 380 ft: rolling country. The highest named summit within 15 miles is Devies Mountain, about 2,780 ft, 6 miles southeast.
The section below crosses 10 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 10×. 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, clastic. Age: Carboniferous, 299 to 324 million years old. About 6 mi of the line.
Limestone, shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 6 mi of the line.
Shale. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.
Sandstone. Age: Carboniferous, 324 to 359 million years old. About 2 mi of the line.
Sandstone, shale. Age: Carboniferous to Permian, 252 to 324 million years old. About 2 mi of the line.
Sandstone, conglomerate. Age: Carboniferous, 299 to 324 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. 4 smaller units along the line are not listed.

A raindrop that lands in Smithfield reaches the Gulf of America by way of York Run, Georges Creek, the Monongahela, the Ohio and the Mississippi: about 2,040 river miles.
970 miles of the trip are on the Ohio.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Smithfield; river miles along the main stem, rounded.
Smithfield has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 24° in January. About 43 inches of rain fall in a normal year.
On November 14 Smithfield normally reaches 55° and falls to 36°. The record high is 78°, in 1993; the record low 10°, in 1986. The most rain on this date, 0.91 in, fell in 1995.
