Genoa’s center stands about 630 ft above sea level. Within three miles the land runs from 600 ft to 660 ft, a difference of 60 ft: nearly flat ground.
Under the town center the state geologic map shows Lockport Dolomite (dolostone), from the Silurian, 425 to 445 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 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone. Age: Silurian, 425 to 445 million years old. About 16 mi of the line.
Dolostone. Age: Silurian, 428 to 445 million years old. About 8 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Genoa reaches Lake Erie by way of Packer Creek and the Toussaint: about 18 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Genoa; river miles along the main stem, rounded.
Genoa has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 20° in January. About 32 inches of rain fall in a normal year.
On November 14 Genoa normally reaches 51° and falls to 34°. The record high is 68°, in 2011; the record low 15°, in 1942. The most rain on this date, 1.17 in, fell in 2011.
