The North Hudson 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 1940. Next is 69° in 2012.
North Hudson’s center stands about 900 ft above sea level. Within three miles the land runs from 870 ft to 2,300 ft, a difference of 1,430 ft: steep hill country. The highest named summit within 15 miles is Mount Marcy, about 5,290 ft, 15 miles northwest.
Under the town center the state geologic map shows Glacial and Alluvial Deposits (unconsolidated), from the Quaternary, less than 2.6 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 6×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Gneiss, metaanorthosite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 17 mi of the line.
Charnockite, gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 6 mi of the line.
Marble. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 0.6 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 0.4 mi of the line.
Age: Mesoproterozoic, 1 to 1.6 billion years old. About 0.4 mi of the line.

A raindrop that lands in North Hudson reaches New York Harbor and the Atlantic Ocean by way of West Mill Brook, the Schroon and the Hudson: about 300 river miles.
Lake on the way: Schroon Lake.
240 miles of the trip are on the Hudson.

North Hudson has a warm-summer humid continental climate. Summer afternoons average 77° in July; winter nights fall to about 4° in January. A normal year brings about 105 inches of snow; with the rain, that comes to about 46 inches of water.
On November 14 North Hudson normally reaches 42° and falls to 24°. The record high is 65°, in 1989; the record low −2°, in 1986. The most rain on this date, 0.85 in, fell in 1959.
