Genesee’s center stands about 1,640 ft above sea level. Within three miles the land runs from 1,600 ft to 2,390 ft, a difference of 790 ft: hilly country. The highest named summit within 15 miles is Bailey Hill, about 2,590 ft, 11 miles southeast.
Under the town center the state geologic map shows Chadakoin Formation (siltstone, 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 19×. 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 8 mi of the line.
Shale, sandstone. Age: Late Devonian, 359 to 384 million years old. About 7 mi of the line.
Sandstone, siltstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 3 mi of the line.
Shale. Age: Late Devonian, 359 to 384 million years old. About 3 mi of the line.
Shale, siltstone, sandstone. Age: Late Devonian, 359 to 384 million years old. About 1 mi of the line.
Siltstone, shale. Age: Late Devonian, 359 to 384 million years old. About 0.9 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Genesee reaches Lake Ontario by way of Cryder Creek and the Genesee: about 150 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 Genesee; river miles along the main stem, rounded.
Genesee has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 13° in January. A normal year brings about 54 inches of snow; with the rain, that comes to about 40 inches of water.
Normals 1991–2020 and records since 1956 at Wellsville, 10 miles north-northwest, 130 ft lower. NOAA, through RCC-ACIS.
