Troupsburg’s center stands about 1,660 ft above sea level. Within three miles the land runs from 1,470 ft to 2,190 ft, a difference of 720 ft: hilly country. The highest named summit within 15 miles is Bailey Hill, about 2,590 ft, 14 miles southwest.
Under the town center the state geologic map shows Machias Formation (shale, siltstone, sandstone), from the Late Devonian, 359 to 384 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 15×. 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: Late Devonian, 359 to 384 million years old. About 9 mi of the line.

A raindrop that lands in Troupsburg reaches Chesapeake Bay and the Atlantic Ocean by way of the Cowanesque, the Tioga, the Chemung and the Susquehanna: about 380 river miles.
Lake on the way: Lake Aldred.
250 miles of the trip are on the Susquehanna.

Troupsburg has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 12° in January. A normal year brings about 82 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Troupsburg normally reaches 47° and falls to 27°. The record high is 67°, in 1994; the record low 7°, in 1939. The most rain on this date, 1.91 in, fell in 1995.
