Pecktonville’s center stands about 490 ft above sea level. Within three miles the land runs from 380 ft to 910 ft, a difference of 530 ft: hilly country. The highest named summit within 15 miles is Cross Mountain, about 2,070 ft, 5 miles northeast.
Under the town center the state geologic map shows Hamilton Group (including Mahantango Formation and Marcellus Shale), and including Tioga Metabentontite Bed, and Needmore Shale, from the Devonian, 359 to 422 million years old.
The section below crosses 13 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 13×. 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, sandstone. Age: Devonian, 359 to 422 million years old. About 5 mi of the line.
Shale. Age: Ordovician, 445 to 487 million years old. About 4 mi of the line.
Siltstone, sandstone. Age: Devonian, 359 to 422 million years old. About 3 mi of the line.
Sandstone. Age: Carboniferous, 324 to 359 million years old. About 3 mi of the line.
Quartzite. Age: Silurian, 422 to 445 million years old. About 2 mi of the line.
Quartzite. Age: Silurian, 422 to 445 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 7 smaller units along the line are not listed.

A raindrop that lands in Pecktonville reaches Chesapeake Bay and the Atlantic Ocean by way of Licking Creek and the Potomac: about 240 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Pecktonville; river miles along the main stem, rounded.
Pecktonville has a humid subtropical climate. Summer afternoons average 87° in July; winter nights fall to about 25° in January. About 36 inches of rain fall in a normal year.
On November 14 Pecktonville normally reaches 55° and falls to 38°. The record high is 75°, in 1989; the record low 10°, in 1920. The most rain on this date, 1.91 in, fell in 1995.
