Prattsburgh’s center stands about 1,470 ft above sea level. Within three miles the land runs from 1,290 ft to 2,180 ft, a difference of 890 ft: hilly country. The highest named summit within 15 miles is Gannett Hill, about 2,320 ft, 14 miles north-northwest.
Under the town center the state geologic map shows Beers Hill, Dunn Hill, Millport, and Moreland Shales; Grimes Siltstone, from the Late Devonian, 359 to 384 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 13×. 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. Age: Late Devonian, 359 to 384 million years old. About 13 mi of the line.
Shale, siltstone. Age: Late Devonian, 359 to 384 million years old. About 10 mi of the line.
Sandstone. Age: Late Devonian, 359 to 384 million years old. About 0.3 mi of the line.

A raindrop that lands in Prattsburgh reaches Chesapeake Bay and the Atlantic Ocean by way of Fivemile Creek, the Cohocton, the Chemung and the Susquehanna: about 370 river miles.
Lake on the way: Lake Aldred.
250 miles of the trip are on the Susquehanna.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Prattsburgh; river miles along the main stem, rounded.
