Middle Smithfield’s center stands about 990 ft above sea level. Within three miles the land runs from 510 ft to 1,180 ft, a difference of 670 ft: hilly country. The highest named summit within 15 miles is Turkey Knoll, about 2,170 ft, 13 miles west-northwest.
The section below crosses 11 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 11×. 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, siltstone, mudstone. Age: Late Devonian, 359 to 384 million years old. About 11 mi of the line.
Graywacke, siltstone. Age: Middle Ordovician to Late Ordovician, 445 to 471 million years old. About 3 mi of the line.
Siltstone, sandstone. Age: Silurian, 422 to 428 million years old. About 2 mi of the line.
Shale, siltstone. Age: Early Devonian to Middle Devonian, 384 to 422 million years old. About 2 mi of the line.
Limestone. Age: Early Devonian to Middle Devonian, 384 to 422 million years old. About 1 mi of the line.
Siltstone, shale. Age: Late Devonian, 359 to 384 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. 5 smaller units along the line are not listed.

A raindrop that lands in Middle Smithfield reaches Delaware Bay and the Atlantic Ocean by way of Bush Kill and the Delaware: about 210 river miles.

Middle Smithfield has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 19° in January. A normal year brings about 42 inches of snow; with the rain, that comes to about 54 inches of water.
On November 14 Middle Smithfield normally reaches 52° and falls to 32°. The record high is 72°, in 1931; the record low 11°, in 1986. The most rain on this date, 1.83 in, fell in 1972.
