Gibson’s center stands about 1,240 ft above sea level. Within three miles the land runs from 1,100 ft to 1,730 ft, a difference of 630 ft: hilly country. The highest named summit within 15 miles is North Knob, about 2,690 ft, 7 miles southeast.
Under the town center the state geologic map shows Catskill Formation (sandstone, siltstone, shale), from the Late Devonian, 359 to 384 million years old.
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.
Sandstone, siltstone, shale. Age: Late Devonian, 359 to 384 million years old. About 24 mi of the line.

A raindrop that lands in Gibson reaches Chesapeake Bay and the Atlantic Ocean by way of Tunkhannock Creek and the Susquehanna: about 260 river miles.
Lake on the way: Lake Aldred.
180 miles of the trip are on the Susquehanna.
