Jerusalem’s center stands about 760 ft above sea level. Within three miles the land runs from 710 ft to 1,560 ft, a difference of 850 ft: hilly country. The highest named summit within 15 miles is Gannett Hill, about 2,320 ft, 14 miles west-northwest.
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 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 11×. 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 Jerusalem reaches Lake Ontario by way of Sugar Creek, the Keuka Lake Outlet, the Seneca and the Oswego: about 130 river miles. From the lake it goes down the St. Lawrence to the Atlantic.
Lakes on the way: Seneca Lake, Cayuga Lake and West Branch Keuka Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Jerusalem; river miles along the main stem, rounded.
Jerusalem has a hot-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 18° in January. About 35 inches of rain fall in a normal year.
On November 14 Jerusalem normally reaches 49° and falls to 34°. The record high is 69°, in 1961; the record low 13°, in 1986. The most rain on this date, 0.59 in, fell in 1997.
Normals 1991–2020 and records since 1942 at Canandaigua 3 S, 17 miles north-northwest. NOAA, through RCC-ACIS.
