Byrnedale’s center stands about 1,300 ft above sea level. Within three miles the land runs from 1,160 ft to 1,980 ft, a difference of 820 ft: hilly country. The highest named summit within 15 miles is Boone Mountain, about 2,410 ft, 8 miles west-southwest.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 14×. 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, conglomerate. Age: Carboniferous, 299 to 324 million years old. About 11 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 8 mi of the line.
Sandstone, siltstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 3 mi of the line.
Shale. Age: Carboniferous, 299 to 324 million years old. About 1 mi of the line.
Sandstone, siltstone, shale. Age: Devonian to Carboniferous, 324 to 422 million years old. About 0.5 mi of the line.

A raindrop that lands in Byrnedale reaches Chesapeake Bay and the Atlantic Ocean by way of Kersey Run, Bennett Branch Sinnemahoning Creek, Sinnemahoning Creek, the West Branch Susquehanna and the Susquehanna: about 290 river miles.
Lake on the way: Lake Aldred.
110 miles of the trip are on the West Branch Susquehanna.

Byrnedale has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 16° in January. A normal year brings about 53 inches of snow; with the rain, that comes to about 46 inches of water.
On November 14 Byrnedale normally reaches 50° and falls to 30°. The record high is 68°, in 2010; the record low 7°, in 1996. The most rain on this date, 1.40 in, fell in 1972.
