North Granville’s center stands about 340 ft above sea level. Within three miles the land runs from 210 ft to 800 ft, a difference of 590 ft: hilly country. The highest named summit within 15 miles is Woodlawn Mountain, about 3,110 ft, 15 miles east-southeast.
The section below crosses 16 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.
Slate, phyllite. Age: Early Ordovician to Middle Ordovician, 459 to 487 million years old. About 5 mi of the line.
Phyllite. Age: Neoproterozoic, 542 to 1,000 million years old. About 4 mi of the line.
Metasedimentary, migmatite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 3 mi of the line.
Paragneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
Graywacke, slate. Age: Late Ordovician, 445 to 459 million years old. About 1 mi of the line.
Shale, phyllite, limestone. Age: Late Ordovician, 445 to 459 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. 10 smaller units along the line are not listed.

A raindrop that lands in North Granville reaches the St. Lawrence River by way of the Mettawee and the Richelieu: about 220 river miles. The St. Lawrence carries it on to the Atlantic.
Lake on the way: Lake Champlain.
100 miles of the trip are on the Mettawee.

North Granville has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 10° in January. About 38 inches of rain fall in a normal year.
On November 14 North Granville normally reaches 47° and falls to 28°. The record high is 67°, in 1973; the record low 5°, in 1905. The most rain on this date, 1.45 in, fell in 2009.
Normals 1991–2020 and records since 1893 from the Glens Falls Area threaded record (Glens Falls/Floyd Bennett Memorial Airport, 16 miles west-southwest). NOAA, through RCC-ACIS.
