Sadsburyville’s center stands about 630 ft above sea level. Within three miles the land runs from 410 ft to 890 ft, a difference of 480 ft: hilly country. The highest named summit within 15 miles is Welsh Mountain, about 1,080 ft, 9 miles north-northwest.
Under the town center the state geologic map shows Felsic to mafic gneiss, from the Precambrian.
The section below crosses 15 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 25×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

Dolostone. Age: Cambrian, 487 to 542 million years old. About 4 mi of the line.
Quartzite, schist. Age: Cambrian, 487 to 542 million years old. About 3 mi of the line.
Gneiss. Age: Precambrian. About 2 mi of the line.

A raindrop that lands in Sadsburyville reaches Delaware Bay and the Atlantic Ocean by way of Buck Run, West Branch Brandywine Creek, Brandywine Creek, the Christina and the Delaware: about 85 river miles.

Sadsburyville has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 24° in January. A normal year brings about 34 inches of snow; with the rain, that comes to about 47 inches of water.
On November 14 Sadsburyville normally reaches 54° and falls to 37°. The record high is 70°, in 1993; the record low 25°, in 2004. The most rain on this date, 0.50 in, fell in 2008.
