Orfordville’s center stands about 890 ft above sea level. Within three miles the land runs from 790 ft to 1,000 ft, a difference of 210 ft: rolling country.
Under the town center the state geologic map shows Ancell Group (sandstone), from the Ordovician, 445 to 487 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. 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: Ordovician, 445 to 487 million years old. About 14 mi of the line.
Sandstone. Age: Ordovician, 445 to 487 million years old. About 8 mi of the line.
Dolostone, limestone. Age: Late Ordovician, 454 to 459 million years old. About 2 mi of the line.

A raindrop that lands in Orfordville reaches the Gulf of America by way of Taylor Creek, the Sugar, the Pecatonica, the Rock River and the Mississippi: about 1,650 river miles.

Orfordville has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 11° in January. A normal year brings about 37 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Orfordville normally reaches 47° and falls to 28°. The record high is 71°, in 1999; the record low 3°, in 1986. The most rain on this date, 1.25 in, fell in 1899.
