The Northville plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
70° on Nov. 11, 2020, the hottest reading for this week of the year since 1948. Next is 68° in 1989.
Northville’s center stands about 810 ft above sea level. Within three miles the land runs from 760 ft to 1,760 ft, a difference of 1,000 ft: steep hill country. The highest named summit within 15 miles is Three Ponds Mountain, about 3,010 ft, 11 miles west-northwest.
Under the town center the state geologic map shows Beekmantown Group (dolostone, limestone), from the Early Ordovician, 471 to 487 million years old.
The section below crosses 10 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 10×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Metasedimentary, migmatite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 10 mi of the line.
Charnockite, gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 5 mi of the line.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 3 mi of the line.
Sandstone. Age: Cambrian, 487 to 497 million years old. About 1 mi of the line.
Age: Mesoproterozoic, 1 to 1.6 billion years old. About 1 mi of the line.
Dolostone. Age: Cambrian to Early Ordovician, 471 to 497 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. 4 smaller units along the line are not listed.

A raindrop that lands in Northville reaches New York Harbor and the Atlantic Ocean by way of Great Sacandaga Lake, the Sacandaga and the Hudson: about 250 river miles.
Lake on the way: Great Sacandaga Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Northville; river miles along the main stem, rounded.
Northville has a warm-summer humid continental climate. Summer afternoons average 77° in July; winter nights fall to about 12° in January. A normal year brings about 60 inches of snow; with the rain, that comes to about 46 inches of water.
On November 14 Northville normally reaches 46° and falls to 31°. The record high is 68°, in 1989; the record low 12°, in 2019. The most rain on this date, 0.78 in, fell in 1988.
