Potter’s center stands about 910 ft above sea level. Within three miles the land runs from 870 ft to 1,520 ft, a difference of 650 ft: hilly country. The highest named summit within 15 miles is Gannett Hill, about 2,320 ft, 10 miles west.
Under the town center the state geologic map shows Genesee Group (shale), from the Late Devonian, 359 to 384 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 12×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

A raindrop that lands in Potter reaches Lake Ontario by way of Flint Creek, the Canandaigua Outlet, the Erie Canal, the Clyde, the Seneca and the Oswego: about 130 river miles. From the lake it goes down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Potter; river miles along the main stem, rounded.
