The West Brooklyn 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.
1° on Nov. 12, 2019, the coldest reading for this week of the year since 1912. Next is 3° in 1986.
West Brooklyn’s center stands about 940 ft above sea level. Within three miles the land runs from 760 ft to 980 ft, a difference of 220 ft: rolling country.
Under the town center the state geologic map shows Ancell Group (sandstone, limestone, dolostone), from the Middle Ordovician to Late Ordovician, 454 to 468 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 63×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, limestone, dolostone. Age: Middle Ordovician to Late Ordovician, 454 to 468 million years old. About 13 mi of the line.
Dolostone, limestone. Age: Late Ordovician, 454 to 459 million years old. About 7 mi of the line.
Dolostone. Age: Early Ordovician to Middle Ordovician, 459 to 487 million years old. About 4 mi of the line.

A raindrop that lands in West Brooklyn reaches the Gulf of America by way of the Green River, the Rock River and the Mississippi: about 1,550 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of West Brooklyn; river miles along the main stem, rounded.
West Brooklyn has a hot-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 12° in January. A normal year brings about 30 inches of snow; with the rain, that comes to about 37 inches of water.
On November 14 West Brooklyn normally reaches 47° and falls to 29°. The record high is 73°, in 1989; the record low 3°, in 1986. The most rain on this date, 2.42 in, fell in 1926.
