Genesee’s center stands about 2,000 ft above sea level. Within three miles the land runs from 1,490 ft to 2,320 ft, a difference of 830 ft: hilly country. The highest named summit within 15 miles is Alma Hill, about 2,570 ft, 12 miles east.
Under the town center the state geologic map shows Oswayo and Venango Formations (shale), from the Late Devonian, 359 to 384 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 17×. 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 13 mi of the line.
Shale. Age: Late Devonian, 359 to 384 million years old. About 11 mi of the line.

A raindrop that lands in Genesee reaches the Gulf of America by way of Little Genesee Creek, Oswayo Creek, the Allegheny, the Ohio and the Mississippi: about 2,220 river miles.
Lake on the way: Allegheny Reservoir.
970 miles of the trip are on the Ohio.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Genesee; river miles along the main stem, rounded.
Genesee has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 13° in January. A normal year brings about 65 inches of snow; with the rain, that comes to about 41 inches of water.
Normals 1991–2020 and records since 1909 at Olean, 11 miles west, 580 ft lower. NOAA, through RCC-ACIS.
