Seneca Falls’s center stands about 460 ft above sea level. Within three miles the land runs from 370 ft to 550 ft, a difference of 180 ft: gently rolling country. The highest named summit within 15 miles is Crozier Hill, about 870 ft, 14 miles west-southwest.
Under the town center the state geologic map shows Akron Dolostone, from the Silurian, 422 to 428 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 34×. 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. Age: Silurian, 422 to 428 million years old. About 8 mi of the line.
Dolostone. Age: Silurian, 422 to 428 million years old. About 4 mi of the line.
Limestone. Age: Early Devonian, 394 to 422 million years old. About 3 mi of the line.
Shale, limestone. Age: Middle Devonian, 384 to 388 million years old. About 2 mi of the line.
Shale. Age: Middle Devonian, 384 to 394 million years old. About 2 mi of the line.
Limestone. Age: Early Devonian to Middle Devonian, 388 to 410 million years old. About 1 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 Seneca Falls reaches Lake Ontario by way of the Seneca and the Oswego: about 75 river miles. From the lake it goes down the St. Lawrence to the Atlantic.
Lake on the way: Cayuga Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Seneca Falls; river miles along the main stem, rounded.
Seneca Falls has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 16° in January. A normal year brings about 57 inches of snow; with the rain, that comes to about 35 inches of water.
On November 14 Seneca Falls normally reaches 47° and falls to 32°. The record high is 65°, in 2005; the record low 14°, in 2019. The most rain on this date, 0.62 in, fell in 1972.
Normals 1991–2020 and records since 1969 at Geneva Research Farm, 12 miles west-southwest, 260 ft higher. NOAA, through RCC-ACIS.
