North Hornell’s center stands about 1,170 ft above sea level. Within three miles the land runs from 1,140 ft to 1,970 ft, a difference of 830 ft: hilly country. The highest named summit within 15 miles is Jackson Hill, about 2,440 ft, 13 miles south-southeast.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 15×. 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 North Hornell reaches Chesapeake Bay and the Atlantic Ocean by way of the Tioga, the Chemung and the Susquehanna: about 380 river miles.
Lake on the way: Lake Aldred.
250 miles of the trip are on the Susquehanna.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of North Hornell; river miles along the main stem, rounded.
North Hornell has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 12° in January. A normal year brings about 82 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 North Hornell normally reaches 47° and falls to 27°. The record high is 67°, in 1994; the record low 7°, in 1939. The most rain on this date, 1.91 in, fell in 1995.
Normals 1991–2020 and records since 1893 at Alfred, 7 miles southwest, 750 ft higher. NOAA, through RCC-ACIS.
